Routing Audio output through mic port

Hey, I’m new to bazzite. My PC’s front audio line out port doesn’t work it’s broken, so I want to route that audio output through front mic line in port, how to do that in bazzite ? Since it doesn’t let hdajackretask to modify boot override (On other linux distros it works fine, may be it doesn’t work due to being immutable?).
Any other way I can achieve this ? Please do let me know.

Thank you.
