How to disable a broken system service in Android 11

tl;dr: the fps_hal init service on my phone is constantly restarting, and since I don't use the fingerprint sensor I want to disable it. Background: Trying to debug my own app on LineageOS 18.1 (Android 11), logcat gave a ton of information about a system service going haywire:

Pulling out some keywords, I ran getprop|grep "init" and all the init services are listed as running except this one:

And that's where I'm stuck. service list gives me nothing to go on, Google gives me nothing, and my knowledge of the Android init procedure and directory structure is close to nil. Can anyone help point me to where this service is managed from, and how to disable it? If the location is SELinux protected, is there a way to patch without re-flashing the entire ROM? Thanks in advance.
