Disable the 'Other' User Option From LightDM

I am currently running LightDM on my AlmaLinux 8.8 machine and I wanted to know if it's possible to remove the Other user option as shown below. I have already tried to edit the /etc/lightdm/lightdm.conf file and set the following options, however with no effect:

[Seat:*]
greeter-show-manual-login = false
greeter-allow-guest=false
allow-guests=false

I have restarted the LightDM service after saving my changes and even rebooted my machine, but no luck.
