It is not possible to make 100% photorealistic renders with Eevee. So if you want an photorealistic result, you should use Cycles. It is a lot slower thain Eevee, but it is the only way to get a photorealistic result. There are a lot of videos on YouTube, on how to reduce the render time.
If you still want to use Eevee, I would not use an HDRI for an indoor scene.
