Switching off GUI in camera software

[Baq_PL]

I'm trying to use my Note 10+ as a camera for streaming and some recording on my PC. Is there a way to use Samsung camera software to output clean picture to USBC --> HDMI but with some effects like live focus. Now it's showing everything I have on my phone screen, all icons etc. I found a 3rd party software OpenCam where u can hide everything but it doesn't have these great live view effects...
