Custom redirect_uri in form for keycloak

Hello colleagues, I am opening this ticket to see if you can help me with this request or if there is a similar request that I have not seen already open.
My problem is that the redirect_uri is not set under the HTTPS protocol, and I have not been able to force a url from the module code or manage to set up a form field to be able to place the url myself.
So, is it feasible or is there a possibility to convert the redirect_uri field into an editable field? Or is there a way to force that value to be armed with the redirect query?

Thanks in advance.
