@dgonzalez85 can you please confirm thats what is needed. Also I found indication that

Looks good! I will test. As we've discussed, MPLS support was mainly in Jericho-based platforms, but seems there are some basic in strata as well: https://www.arista.com/en/support/toi/eos-4-23-0f/14327-mpls-support-on-x-series-switches. So good to add a note to review platform support. thanks!
