Microsoft note this behaviour and have some sort of workaround in their NPS MFA 
extension:

Really though, doing MFA for RADIUS is a square peg in a round hole, use MFA to 
provision a client cert and do EAP-TLS instead.

Subject: [WIRELESS-LAN] ISE-NPS-Azure MFA

A question not directly related to Wi-Fi, but related to ISE which seems to be 
something some of you use.

We are currently authenticating a VPN test group via ISE through NPS servers 
(defined as a token server).
The goal is to do MFA with Azure through the Authenticator app on people’s 
phones.
Everything works, but Authenticator pops up for confirmation, sometimes 2 to 3 
times, even if one has accepted the first confirmation…

I would like to have feedback from people who used something like that and have 
solved the multiple Authenticator prompts.

Thank you
