Quoted from #12433:
Uprobes is the user-space counterpart to kprobes: they enable instrumentation applications (such as 'perf probe') to establish unintrusive probes in user-space binaries and libraries, by executing handler functions when the probes are hit by user-space applications.
( These probes come in the form of single-byte breakpoints, managed by the kernel and kept transparent to the probed application. )
IMHO this can be safely disabled, as there is little if any need to debug userspace programs _that_ deeply on an IPFire machine.
Fixes: #12433

The kernel ignore this option and reset it to "Y" because UPROBE_EVENTS select this. UPROBE_EVENTS is enabled by default and needed for perf tools so i think it should enabled.
