Is it possibile to access walk_speed setting of Walk Navigation mode via python API? (I know how to activate the Walk mode by script, but I want to change the walk speed).

Sure, you can access all settings of WalkNavigation via Preferences. Recommend use the python console to figure out:

>>> C.preferences
<bpy_struct, Preferences at 0x1108d8a28>

walk_speed
use_gravity
walk_speed_factor
...


Demo on how to call bpy.ops.view3d.walk() from a script and set the walk_speed to 23 (default is 2.5) by overriding the context of the operator (the actual area and the region):

import bpy

C = bpy.context
