Is transit gateway available under the co-existence of Express Route Gateway and VPN Gateway?

I am planning to use hub and spoke network topology in my Azure environment. At the same time, it is required to establish a connection between my on-premise network and Azure environment using Express Route with S2S VPN as the backup.

I wonder if I still can use my S2S VPN/Express Route as the transit gateway in this scenario? If it is okay, can I choose S2S VPN gateway as my transit gateway? Thanks.

Azure ExpressRoute
Azure ExpressRoute

    I understand that you want to setup a Hub and Spoke network with Azure ER and Azure VPN as the backup. This is absolutely possible to setup. Here are some reference documentswith a similar setup:
