Modify Transit Gateway Properties After Creation
When a Transit Gateway (TGW) is created, either in CloudFormation or in the console, several properties can be configured, specifically:
- AutoAcceptSharedAttachments
- DefaultRouteTableAssociation
- DefaultRouteTablePropagation
- Description
- DnsSupport
- VpnEcmpSupport
Once the TGW is created, Is there a way for a user to change these properties after creation without having to re-create the TGW again?

Transit Gateway (TGW) allow the modification of certain properties after the creation.
When you modify a transit gateway, the modified options are applied to new transit gateway attachments only. Your existing transit gateway attachments are not modified.
Refer to Modify a transit gateway in the user guide or the AWS CLI/API docs for options that can be modified after creation.
