HCI - No public Access to resources

[TimAbmgf]

My tenant policies do not allow for public access to storage accounts or key vaults.
While I was deploying the custom template (with Parameters) I had to make changes disabling access
"publicNetworkAccess": "Disabled",

I got as far as executing the validated template, but it fails because the keyvault is reflecting as not being created:
{
"code": "UpdateDeploymentSettingsDataFailed",
"message": "Deployment Settings validation failed.",
"details": [
{
"code": "UpdateDeploymentSettingsDataFailed",
"target": "/subscriptions/27e4e2c5-92d3-4de7-bda8-0cc2a967a595/resourceGroups/rg-HCIboxEast-TimA-poc/providers/Microsoft.AzureStackHCI/clusters/hciboxcluster",
"message": "Failed to create deployment settings. \nValidation status is {Status=Error, Steps={Name=Error, Description=Error executing Request: Validate, FullStepIndex=0, StartTimeUtc=10/23/2024 10:49:49 PM, EndTimeUtc=NA, Status=Error, Exception=System.Collections.Generic.List`1[System.String], Steps=}}. \nDeployment Status is {Status=, Steps=null}"
}
]
}

Is public Access required?
