Compared to Android 11 one ui 3.1 is running well for me than one ui 4.0 and system is lagging

Absolutely correct

[mahi1509]

KNOX won't trip until you flash any Custom ROM.
Installing official Firmware won't harm Knox.

Will use ODIN for downgrade

[mahi1509]

Yeah
Using Odin to flash Official firmwares won't harm knox

[AlenSony소니알렌]
