Someone suggested I reset the cmos battery and it says to take the battery out and I’m not sure if this is the battery. Is this correct? ( I have a strix b550-f gaming motherboard)

How would I reset cmos on my ASUS motherboard

there should be a jumper on the motherboard which can be set > power on > set the jumper back > power on. the motherboard manual will tell you where the bios clear jumper is

edit: makesure you power off the machine before changing the jumper

or easiest and lazy way would be to remove the power form the machine then remove the CMOS (silver coin) battery. press the power button, the fans will probably spin for a second, this should clear your bios.

reconnect the battery and power and power on as normal and make any changes you need to your bios
