Centos 8 - php 7.2 upgrade to php 7.3|php 7.4 by Appstream repo

New to follow here.
nginx , centos 8 , no remi,
Nextcloud 20.0.2 initial installed, upgraded to 20.0.4 by gui updater.

Want to install “Mail” App, but centos 8 defaults to php 7.2 which doesn’t meet the requirement.

Found centos 8 appstream can do the following, haven’t run them all yet.

dnf module reset php

dnf module enable php:7.4

Anyone has similar experience doing this php migration live on a workable NC and success?
