NEED HELP PLEASE
I have PHP Versions 5.6, 7.2.24 and 7.3.33 installed but need to ADD 7.4 and 8.1

I’ve gone to webmin > software package updates then choose Package Repositories and clicked the PHP 8.1 and Enabled it
then
using the command
yum install rh-php81 rh-php81-php-mysqlnd

It comes back with
Loaded plugins: fastestmirror

Error: Nothing to do

PLEASE HELP what do I do?
