SCTP on Azure VNet S2S connection

Hello All

I am working on a project to migrate a telco software to Azure and I have a specific technical question in this context.

1. Does a direct ExpressRoute connection between a corp on-premises network and an Azure VNet allow/support SCTP (Stream Control Transmission Protocol) protocol?
2. If not, does a VPN Site-to-Site connection allow/support SCTP?
3. Can we create an IPSec tunnel on either of these connections?

Thanks in advance
