Switch port configuration for 9120AX flex mode & inline sgt tagging

What should be the basic configuration for a Cat9k port that connects to a 9120AX AP configured for flex mode and inline SGT tagging?

.1q trunk & no-Auth i guess...
but not sure part "inline SGT tagging" is supported. the reason is EN has no other means to figure SGT value for egress frame it needs to construct VXLAN packet to send further other than that by learning SGT assigned by Fabric AP & transmitted to EN in VXLAN packet header to EN (EN decapsulate VXLAN packet & learns SGT inserted into VXLAN-header by Fabric AP . EN cannot learn SGT within CMD of .1q frame constructed by flexconnect AP). u can try to overcome this with assigning SGT based on VLAN or some other local to EN approach.
@jedolphi any other thoughts?
