• Name: GCPSovereignCloudInstall (with "Install" prefix as required for installer feature gates)
• Location: features/features.go:875-881
• Jira Component: "Installer"
• Contact: barbacbd
• Enhancement PR: CORS-4434: Add GCP Sovereign Cloud support enhancement enhancements#1977
• Enabled in: TechPreviewNoUpgrade and DevPreviewNoUpgrade

Generated Files Updated:

• features.md - Documentation showing the feature gate is enabled in TechPreview and DevPreview
• Multiple feature gate manifest files for both Hypershift and SelfManagedHA cluster profiles

The feature gate follows the same pattern as the existing FeatureGateAWSEuropeanSovereignCloudInstall
for AWS sovereign cloud support, making it consistent with similar installer features.
