Hope you are using the advanced template

add a folder themes in the backend folder

make a subfolder with the theme name and make sure you have the layouts folder in that folder

ie your new layout folder path will be

backend/themes/themefoldername/layouts

in the folder backend/config/main.php

 'components' => [

        'view' => [
            'theme' => [
                'basePath' => '@backend/themes/themefoldername',
                'baseUrl' => '@backend/themes/themefoldername',
                'pathMap' => [
                    '@backend/views' => '@backend/themes/themefoldername',
                ],
            ],
        ],...

if you want to keep it in the web folder also you can do that,but make sure you change the path accordingly

In advance template there is separate configuration for frontend and backend theme integration.

Frontend theme integration => "frontend/config/main.php" file :

'components' => [ 
    'view' => [
            'theme' => [

                'pathMap' => [
                    '@frontend/views' => '@themes/frontend/views', // need to // set alias first in your bootstrap.php file
                ],
            ],
        ],
],

Backend theme integration => "backend/config/main.php" file :

'components' => [ 
    'view' => [
            'theme' => [

                'pathMap' => [
                    '@backend/views' => '@themes/backend/views', // need to set // alias first in your "common/config/bootstrap.php" file
                ],
            ],
        ],
],

While coding take care of comments and directory paths and no need to write baseUrl or basePath.
