Installing Alt-PHP and its extensions on CentOS7 running Litespeed

I need a professional to install Alt-PHP 8.1 and its modules/extensions on my CentOS7 server running Litespeed. This is an application requirement for one of my websites. This ALT-PHP is only for a specific domain/account/website and not entire server. My server has Cpanel v110.
I am not using Cloudlinux or Almalinux. I am hosted at Liquidweb.

Key Tasks:
- Install Alt-PHP 8.1 on a CentOS7 server for a specific account/domain of mine
- Ensure compatibility with Litespeed
- Install all default modules/extensions particularly mysqlnd & nd_pdo_mysql
(Note: nd_pdo_mysql is not pdo_mysql and is different)
- Transfer and install existing modules from my current 8.1 PHP
- Let me know how to access it to make changes if needed in future (Will it be selectable in Cpanel/WHM? how to enable/disable extensions)

Ideal candidate should have:
- Extensive experience with CentOS7 and Litespeed
- Proven track record in PHP installations
- Familiarity with Alt-PHP and its modules
- Ability to transfer and install custom modules

Please NOTE: I am not running Cloudlinunx but i specifically need these two modules for a mobile app compatibility:
1) "nd_pdo_mysql (not "pdo_mysql")
2) mysqlnd
