Mine is a Sony A7-III, the setting is called Anti-flicker shoot. I believe many modern mirrorless systems have the capability.
However, I wouldn't say "oh that's easy", because A7-III has two realtime DSPs, and one of them is directly responsible for things like real-time focusing, face/object/eye recognition and real time tracking, etc. So, I believe that DSP is handling the flicker detection as well.
...and A7-III is the "entry level" member of its generation. higher end models have more computing power than that.
