You can only delete an existing tabular model using SQL Server Management Studio (SSMS).
These steps describe how to delete a model from a server by using SSMS.
Prerequisites - Download SQL Server Management Studio (SSMS)
Step1: In SSMS > Object Explorer, click Connect > Analysis Services.
Step2: In Connect to Server, paste in the server name, then in Authentication, choose Active Directory - Universal with MFA support, enter your username, and then click Connect.
Step3: In Object Explorer, right-click the adventureworks
sample database, and then click Delete.
Reference: Azure Analysis Service - Clean up resources
Hope this helps. Do let us know if you any further queries.
