Change NVRAM to show correct OC version without fully resetting it?

Hello there.

I am running BigSur 11.4 with OC 0.7.1 on my Thinkpad T440s and i am really pleased, everything works well and i didn´t use windows 10 for 2 weeks now, i may be finally managing to get away from windows for good!

I just noticed that Hackintool says that my OC Version is 0.6.3 and i already found that i need to reset NVRAM, but there seems to be the risk of bricking my thinkpad if i do so, so is there a way to specifically delete that one information from nvram?

also, has anyone here ever bricked his thinkpad like this? i replaced my mainboard last year because it did not boot anymore (like when i pressed the power button nothing happened exept the power led lighting up if i remember correctly), maybe i did brick it like that back then?

thanks in advance!
