Does a EMEA BR1 5G work in the US?

There are two different models of BR1 Pro 5G MAX-BR1-PRO-5GD-T-PRM and MAX-BR1-PRO-5GH-T-PRM the 2nd being for use in the US.

Apart from the US version being advertised as supporting 5G Standalone (why not the EMEA version?) is there much of a difference? Can I take the EMEA version to the US get 5G/4G fine?

The US certification system and SIM activation process makes my eyes hurt just thinking about it…
