As your question is about the Arch Linux and it doesn't have the a2enmod & a2dismod. I am gonna providing working answer in the arch:

I assume you have installed php7 & php8 and just want to make apache to use the version 7.

first uninstall apache-php module and install the right one.

sudo pacman -R php-apache  
sudo pacman -S php7-apache

then in the /etc/httpd/conf/httpd.conf change the module name:

from :

LoadModule php_module modules/libphp.so
Include conf/extra/php_module.conf
AddHandler php-script php

to:

LoadModule php7_module modules/libphp7.so
Include conf/extra/php7_module.conf
AddHandler php7-script php

after that you can reload the server:

sudo systemctl reload httpd
