SPN for CRMDeploymentServiceAppPool and CRMAppPool on the same machine

I am installing Dynamics CRM 365 v9.1 and see this security consideration site:

 "The service account may need an SPN for the URL used to access the website that is associated with it."

https://docs.microsoft.com/en-us/dynamics365/customerengagement/on-premises/deploy/security-considerations-for-microsoft-dynamics-365?view=op-9-1#BKMK_D

The site says that it may need to do this for Deployment Web Service (CRMDeploymentServiceAppPool Application Pool identity) and Application Service (CRMAppPool IIS Application Pool identity)

Both services are on the same machine, therefor I cannot add something like this twice

HTTPS/servername

HTTPS/servername.contoso.com

HOST/servername

HOST/servername.contoso.com

Does anyone have an example how the SPN’s need to be added for these services?
