If the Blackmagic Design firmware update instructions don't say you need to remove the SD card, I'd ignore the youtubers. They're probably just copying each other's advice.
I don't have the BMPCC 4K but I've updated my original BMPCC and my two BMMCCs multiple times with the SD card inside, never had any problems.
