OK re-tried today, learned you can turn off the rear red indicator running lights but that leaves you with no rear night time lights.
Did a search on You tube and found (below) a good tutorial from Carl at Just the way it is.

I didn't realise that the rear central light is only a brake light. The rear night time lights are on the indicators.
I was hoping you could code the rear light to be a normal light and brake light.
If you want the rear central light to act as a normal rear (nightime) running light and a brake light you (at the moment) need to get a Weiser Technik EXT-Run-on Module BMW GS or as i have ordered a WEISER WIZARDS – BMW Multifunction Indicators Re-Sequencing Modules R1250 GS/A 2021+ (Reactivate Module Only) £75
Think this is plug and play and easier to fit than the quoted Run on module that taps into the cables.
Once fitted I'm hoping i can then zero out the red indicators and have them work just as yellow indicators.
On the Wieser web site seems to show that when indicating it auto matically cancels out the red running light, so may just use them as displayed.
Reactivate Module for the BMW R1250 GS/GSA 2021-24. Available in both Front, Rear and Combo Kits. This “PLUG + PLAY” interface module massively improve the effectiveness of the OEM multifunction indicators and taillight by re-sequencing their functionality. Providing a no nonsense, no confusion...
