sqlsrv error on apache2

I've recently switch to CI4 and am also deploying to a apache2 server instead of IIS like I have in the past.

I have a simple boilerplate app that I converted to CI4 that connects to a database on my domain. Here is my config:

Code:

public array $default = [
        'DSN'      => '',
        'hostname' => 'db-sql',
        'username' => 'myuser',
        'password' => 'mypassword',
        'database' => 'mydatabase',
        'DBDriver' => 'sqlsrv',
        'DBPrefix' => '',
        'pConnect' => false,
        'DBDebug'  => (ENVIRONMENT !== 'production'),
        'charset'  => 'latin1',
        'DBCollat' => 'latin1_general_ci_as',
        'swapPre'  => '',
        'encrypt'  => false,
        'compress' => false,
        'strictOn' => false,
        'failover' => [],
        'port'    => 1433,
    ];

All of this works on my local xampp webserver, the page loads and connects to the database.
When moving this to my remote apache2 server, my page will load but an api call that gets data from the database fails.
I am getting this error:

Code:

Class \"CodeIgniter\\Database\\sqlsrv\\Connection\" not found

I have php 8.1 installed on this machine, as well as the relevant sqlsrv driver.
Here is some data from my phpinfo()

Everything looks setup to me, but it's my first time. Is there something I'm missing?

Your database config DBDriver is invalid.
It should be SQLSRV, not sqlsrv.
