How do I clear the CMOS/RTC RAM to reset BIOS settings on the ROG Strix B450-F Gaming?

To clear the RTC RAM, turn off the computer and unplug the power cord, then short-circuit pin 1-2 on the CLRTC jumper with a metal object or jumper cap for about 5-10 seconds. Plug the power cord back in, turn on the computer, and hold down the <Delete> key during boot to enter BIOS setup and re-enter your data. If this does not help, remove the onboard battery and move the jumper again to clear the CMOS RTC RAM data, then reinstall the battery afterward. (Page 1-9)
