How to make it so that an EnumProperty is not animatable

Question

I've coded this enum property using this code:

class RuleCondition(PropertyGroup):
    data_type: EnumProperty(
        name="Condition Object Type",
        description="The type of data",
        items=[
            (
                RuleIDStrings.OBJECT,
                'Object',
                "The condition should be based on an object being present or not"
            ),
            (
                RuleIDStrings.MATERIAL,
                'Material',
                "The condition should be based on an object being present or not"
            )
        ],
    )
...

And it shows up like this in the interface:

Is there a way that I can make it non-animatable so that the little circle next to it allowing for keyframes doesn't show up? I've tried setting the is_animatable flag to False:

    data_type: EnumProperty(
        name="Condition Object Type",
        description="The type of data",
        items=[
            (
                RuleIDStrings.OBJECT,
                'Object',
                "The condition should be based on an object being present or not"
            ),
            (
                RuleIDStrings.MATERIAL,
                'Material',
                "The condition should be based on an object being present or not"
            )
        ],
        is_animatable=False
    )

But the EnumProperty can't register when I do that. It also doesn't allow me to use a colon instead of an equals sign (it says "positional argument follows keyword argument"). Any thoughts on how to make it so that this property isn't animatable?

UPDATE: When I pass an empty options parameter as shown below, I get the following error.

class RuleCondition(PropertyGroup):
    data_type: EnumProperty(
        name="Condition Object Type",
        description="The type of data",
        items=[
            (
                RuleIDStrings.OBJECT,
                'Object',
                "The condition should be based on an object being present or not"
            ),
            (
                RuleIDStrings.MATERIAL,
                'Material',
                "The condition should be based on an object being present or not"
            )
        ],
        options={}
    )
...

Sending: {'type': 'enableFailure'}

TLDR; Add options=set() as a parameter when defining the EnumProperty to avoid passing the default {'ANIMATABLE'} value.

bpy.props.EnumProperty is a function that takes these arguments:

EnumProperty(items, name="", description="", default=None, options={'ANIMATABLE'}, override=set() .. function:: EnumProperty(items, name="", description="", default=None, options={'ANIMATABLE'}, override=set(), tags=set(), update=None, get=None, set=None)

You need to remove the attempt to set is_animatable directly and instead pass options={} as an argument. Unless you want to set any options from HIDDEN’, ‘SKIP_SAVE’, ‘ANIMATABLE’, ‘ENUM_FLAG’, ‘LIBRARY_EDITABLE, in which case you pass them in the options set.

    data_type: EnumProperty(
        name="Condition Object Type",
        description="The type of data",
        items=[
            (
                RuleIDStrings.OBJECT,
                'Object',
                "The condition should be based on an object being present or not"
            ),
            (
                RuleIDStrings.MATERIAL,
                'Material',
                "The condition should be based on an object being present or not"
            )
        ],
        options=set()
    )
