@NBL I had discussion internally and got below response from our internal team:
Shared Image Gallery is not supported in WVD classic, we don't invest in new features for WVD classic now, but we will maintain e.g. the ARM templates if there are any issues.
Whilst its not "integrated" you can modify the Classic ARM template to interact with the SIG and pull images:
You can use this template: https://github.com/TomHickling/RDS-Templates/tree/master/wvd-templates/Create%20and%20provision%20WVD%20host%20pool - originally created by the illustrious John Jenner (HE/HIM)
We recommend customers to deploy new host pools into the WVD ARM version.
Hope it helps!!!
