Is there a way to set rendering resolution in Unity VR?

I'm developing VR game for quest 2 and quest 3 and found if I run game as normal Android app and show it in window mode, it is more clear than what I see it in VR mode.

I found even I change Unity URP render scale to 2x, it's still not the same in window mode.

At last, I change the default texture height by ADB, and everything in VR mode is clear now.

So my question is: it here any way to change this defualt texture size in Unity? My game need the as max rendering resolution as possible, the render scale in URP doesn't do the best.
