Salesforce has a feature to "Defer Sharing Calculations" ( https://help.salesforce.com/s/articleView?id=sf.security_sharing_defer_sharing_calculations.htm&type=5 )

It would be awesome if Gearset Pipelines could have an option to utilize this, if sharing rules are included in Deployment, defer sharing rules for any validation / deployment, re-enable and recalculate after deployment
