Yes, you can using graph api for this.

1. you should have a service principle grant persmission first
2. call graph api to get token
3. using the token to call the specific api
4. try to use powershell as below

GET https://graph.microsoft.com/v1.0/sites/{site-id}/getByPath('/')/effectivePermissions/user({user-id})
