Can we change route table of the VPC created by Qovery?

We want to start using MongoDB from MongoAtlas. The best way to create a secure connection is to use their VPC peering feature. We initiated VPC peering from MongoAtlas, accepted the invitation and modified our routing table according to their guide.

  1. Will the Qovery revert back the routing table configuration when performing cluster update or other maintenance?
  2. Qovery allows installing on existing VPCs, can we unlink the VPC originally created by Qovery and start managing it ourselves?
