Specifying Regulatory Domain for Netgear X4S R7800

Can anyone confirm that there is no fixed, hardcoded, definition for the Regulatory Domain/country code on a Netgear 'Nighthawk' X4S R7800?

I'm considering transitioning to an R7800 to run my network.

At present, I'm running (without issue) with a Linksys WRT3200ACM. However, it was sourced from a UK seller on eBay & the device is reporting as hard configured for FR, not a big deal as UK - FR reg domain specs show little difference &, for now, I believe my configuration avoids any infringement of UK licensing.

country FR: DFS-ETSI
