I use something similar and all transfers between Teams users work fine:
onreply_route[PBX_REPLY_TO_TEAMS] { subst('/^Allow:\s(.*),\sREFER(.*)$/Allow:\s\1\2/ig');
Teams thinks that we don't support the refer method and it manages the transfers.
I have not tried the external transfers but I think if the SBC rules are ok, it must be managed by Teams.

Outbound call transfer fixed !
if can helps :
if(status=="200"){ remove_hf("ALLOW:"); append_hf("ALLOW: INVITE,ACK,OPTIONS,CANCEL,BYE,NOTIFY \r\n","CONTENT-TYPE"); }
last but not least i need to fix transfer for incoming calls
so in my case i use rtpengine for manage RTP > SRTP conversion .. so my issue in if i try to transfer pbx send me "not acceptable here" if i remove ice PBX accept the INVITE but Teams require SRTP, so does anyone know how to get it to work ?
Thanks you !!!

Direct Routing supports two methods for call transfer:
Option 1. SIP proxy processes Refer from the client locally and acts as a Referee as described in section 7.1 of RFC 3892.
With this option, the SIP proxy terminates the transfer and adds a new Invite.
Option 2. SIP proxy sends the Refer to the SBC and acts as a Transferor as describing in Section 6 of RFC 5589.
With this option, the SIP proxy sends a Refer to the SBC and expects the SBC to handle the Transfer fully.
The SIP proxy selects the method based on the capabilities reported by the SBC. If the SBC indicates that it supports the method “Refer”, the SIP proxy will use Option 2 for call transfers.
The following is an example of an SBC sending the message that the Refer method is supported: ConsoleCopia
ALLOW: INVITE, OPTIONS, INFO, BYE, CANCEL, ACK, PRACK, UPDATE, REFER, SUBSCRIBE, NOTIFY
If the SBC doesn’t indicate that Refer as a supported method, Direct Routing will use Option 1 (SIP proxy acts as a Referee) . The SBC must also signal that it supports the Notify method:
Example of SBC indicating that Refer method is not supported: ConsoleCopia
ALLOW: INVITE, ACK, CANCEL, BYE, INFO, NOTIFY, PRACK, UPDATE, OPTIONS
so i try to add "REFER" in the allow ì: heder but still no luck Davide

I think Teams doesn't send REFER messages. Transfers are managed directly by Teams. When you transfer a call you can send to a Team user instead to a SIP extension.
