Cannoset preloadedOSImageName in OKD Deployment with Nutanix

[rasystems1]

Describe the bug

Hi everyone,
I am currently deploying OKD in IPI mode on the Nutanix platform. I want to deploy OKD using an image template that has already been uploaded to Nutanix. I encountered the following error. I realized I needed to clone the image within Nutanix by providing the URL for the corresponding template—in my case: https://rhcos.mirror.openshift.com/art/storage/prod/streams/c10s/builds/10.0.20251103-0/x86_64/scos-10.0.20251103-0-nutanix.x86_64.qcow2

After uploading it and setting the following parameter in the install-config (I named it okd-scos):
preloadedOSImageName: okd-scos

When running the deployment, I consistently get this error:
FATAL could not retrieve cluster infrastructure variables: could not retrieve dependency "Cluster infrastructure variables": could not generate asset "Platform provisioning check": platform.nutanix.preloadedOSImageName: Invalid value: "okd-scos": could not validate preloaded rhcos image: could not obtain rhcos image version from source_uri of preloaded object okd-scos https://rhcos.mirror.openshift.com/art/storage/prod/streams/c10s/builds/10.0.20260806-0/x86_64/scos-10.0.20260806-0-nutanix.x86_64.qcow2

Upon reviewing the code, I found that the openshift-installer always checks that the name starts with rhcos rather than scos. Therefore, a workaround would be to download the file from an HTTP server but rename it to start with rhcos.

PR was raised! Currently waiting on approval from installer team

The PR is not enough. The whole repo has many hardcoded RHCOS assumptions.
I've reached out to SPLAT team for better fix
