SQL Cluster Best Practice windows updates

Question

I am trying to patch a 6 node SQL Geo cluster. The trick is to ensure that location 1 always maintain's node majority. In order to do that 3 of the servers need to be online and hold Majority. I need to be able present the windows updates to all the SQL servesr and have me manually start the install process and reboot. This way I will ensure node majority is never lost. If i do this automatically I might lose majority if the server are all in different parts of the reboot cycle thus bringing the cluster down. What settings do I need for my advisement to ensure the servers in a collection can see the updates but I control the download, install, and reboot of the servers manually?

 

Location 1

SQLServer01

SQLServer02

SQLServer03

SQLServer04

 

Location 2

SQLServer05

SQLServer06

 

TIA
