set the FIRMWARE_RELEASE_STATUS environment variable. eg
Note though that rpi-eeprom and bootloader firmwares are included in the images so if you want to use current bootloader versions you have to use nightly images (LE 12.0.1 ships with latest firmware from about half a year ago, current LE12 and LE13 nightlies have 2025-01-08 latest bootloader ATM)
If you want to use more recent versions just download them from rpi-eeprom github and use rpi-eeprom-update -f YOUR_PI_EEPROM.BIN
