I've got a weird display flickering, for many times when the laptop is turning on it adjusts the contrast or something with brightness, blacks out several times and when it's ready (turned on after password - everything is loaded at that point) after a while monitor blacks out for a while again

I can't see any problem while working. Only when it starts up.

On my previous lapton MacBook Pro 13 Intel i5 I never noticed such kind of thing happening for years.

I tried to find something on the internet but apparantly I can't reset neither NVRam nor SMC with my M1 chip

Maybe you could give any hints on how I can conquer that flickering or that's ok for all new MacBooks?

No SMC or NVRAM on the M1/M2 SoC the equivalent is—

Shut down, close the lid 30 secs+ , reboot as normal.
