Intriguing question 
Crafters have been equipped with VW MQB based controllers since MY. So the BCMs are somewhat reconfigurable via adaptations - and there are plenty of those. Probably would need some trial and error experimenting.
Indeed, there are a couple of mentions in the adaptations which relate to remote's centre button (HDF-Funktaster). Unfortunately, having only the adaptation map of a vehicle doesn't show what options are actually available - just what's the current value.
E.g.
Would need to hook up VCDS into the BCM and then look into candidate channels to see what's possibly available in there.
PS. Quite impressive number of channels in the above BCM (from a MY23 Crafter) - almost 2800 channels to mess around with

Grabbed from Crafter 2023 auto relock after 60s how to off?
PS2. Unknown to me if altering the BCM on Crafter is already locked by VAG's SFD mechanism - I believe not yet on Crafter/TGE. The protection would be shown in VCDS Auto-Scan on controller's VCID line as below (the snippet is not from Crafter)SFD - Schutz Fahrzeug Diagnose - Vehicle Diagnostic Protection
Wow @mmi I have obviously sparked your interest in this possibility!Intriguing question

I do own an up to date fully functioning version of VCDS and, when time allows, can supply adaption maps etc. from our 2023 TGE and I'm willing to experiment. However I'm no expert and during the next couple of months have rather a lot of other commitments.
Your thoughts and assistance will always be appreciated.
