Missing Headphone/3.5mm Output option on RPi 2

[ravishi]

I'm using an old Raspberry Pi 2 w/ Moode 8.3.9 (32-bit Bullseye). I'm not seeing a Headphone / 3.5mm output option. I only have a "I2S audio device" option. I see this issue has been discussed before but I can't use the previous solution of switching to "Firmware mode (Legacy)" since that config option doesn't exist on the System Config tab. Any other workarounds?
