Django 4.2.6: Installing Different Admin Templates for Different Custom Admin Sites

Question

I'm facing an issue while trying to install different admin templates for different custom admin sites in Django. Specifically, I want to use the default django.contrib.admin template for the default admin site and enable django-jet-reboot for a custom admin site.

The problem I'm encountering is that when I install django-jet-reboot, it gets enabled for all admin sites, including the default one.

Could someone please guide me on how to correctly install and apply different admin templates for distinct custom admin sites in Django?

Thank you in advance for your assistance!

I have tried to write a custom djanto template loader that reads a field from the settings: The following is a configuration that assiciate a given admin site with a corresponding template

#settings.py
.............
ADMIN_TEMPLATE_ASSOCIATION = {
    'admin': {
        "template": "django.*",
        "exclude_templates": [
            'jet.*',
            'jet.forms',
            'jet.dashboard',
        ]
    },
    'first_admin': {
        "template": "jet.*",
        "exclude_templates": [
        ]
    },
}
..............

            template_dirs = [Path(app_config.path) / 'templates'] + template_dirs
        template_dirs.extend([Path(app_config.path) / 'forms' / 'templates'])
    return template_dirs


class CustomLoader(FilesystemLoader):
    def get_dirs(self):
        print(get_app_template_dirs())
        return get_app_template_dirs()


class Loader(FilesystemLoader):
    def get_dirs(self):
        return get_app_template_dirs("templates")

There are two problems:

1. The main probleme I dont know how to get the active admin site from the loader file.
2. when I pass the admin site manualy it works but the page displays with no formatting
