[ssh_x509] UsePAM sshd_config

[ssh_x509 at roumenpetrov.info]

Looks like UsePAM cannot be used in a Match block.

I currently have machine accounts and user accounts. Machine accounts use
SSH keys whereas user accounts use X.509:

Here is an abbreviated sshd_config file:

...
PubkeyAlgorithms x509v3-sign-rsa
...
UsePAM no
...
Match Group *,!users
  PubkeyAlgorithms ssh-rsa,rsa-sha2-256

Is there another way to create new /home directories without setting UsePAM
yes?
