Edit default views

Hi.

Im pretty amazed by Axelor, but I need to modify the default forms to include some customs field and remove/hide other, but using the Studio is not possible, is there any way to modify this to allow the changes from the studio app? I installed the version 8.1.5 from docker hub.

Also I would like to modify the nested field inside other custom forms, is there any way to do it from studio, I do not have access to the backend.
.
Thanks a lot for the help!
