If you want to have them enabled on boot, sure.

What distros enable tracepoints by default?
If you want to enable a tracepoint on module load simply do:
modprobe mymod trace_my_tracepoint=1
Otherwise modify your modprobe.d directory. This is the way users have
been doing module parameters for years.
That's pretty simple to me.
