Register button on start

Hello everyone,
On the Traccar login form, we can see a Register button.
Any user can register and access the server.
Is there any way I can prevent users from registering using this Register button?
Thank you

Yes, disable registration in the server settings.

Thank you Anton,
I believe you're referring to the server config file.
I have accessed Configuration File and cannot find any related setting.
Can you please help me?

I'm not referring to the configuration file. I'm referring to server settings (Settings > Server menu).

Found it!
Thank you very much
