[Ground-station] Potential Phase 4 - Gateway interference

With AREx and Lunar Orbiting Platform Gateway (usually just called
"Gateway") developing and progressing, Paul KB5MU brought up something we
need to check on.

If Gateway uses the 10GHz amateur downlink (and they plan to) how much
impact do other 10GHz payloads present? QO-100, Phase 4X, CatSat, etc.?

I think any interference or outages are going to be very small, but I'd
like to have an answer before someone like ARISS asks.

If we all use DVB-S2/X, then it would seem that there would be a potential
for brief interference.

Assuming 10GHz downlinks from Gateway
1) how often would potential interference occur for GEO, HEO, LEO?
2) is there anything that we (or Gateway) should do about it?
3) is there anything that we (or Gateway) could do about it?

Goal: Quantify and document.
