Disable Midi song position pointers on specific channels


I’m trying to control a (sensitive) hardware synth that can get easily drawn when receiving MIDI it does not expect.

I’m using a midi quadra trough device where I send all MIDI signals (clock etc…). On the synth specific channel, I managed to disable everything except the note on/off however it seems that the option song position pointers in the preference is causing a problem.

Is it possible to disable it on a specific channel?
