So I checked the other default helicopters as well. The Chinook and Ericsson both support FTR. Even the MSFS2020 Bell 47J Local Legend supports it, which makes me think that any helicopter with trim support will also have FTR.
The HPG H225 is a bit different. It has the custom HPG Stability Augmentation System (SAS) implementation, currently with follow-up trim enabled for both hover and cruise. In the H145 and H160, you can choose on the HPG tablet if you want it for hover (realistic), cruise or both. This means that it flies more liek an A320: point the nose where it should go, and the SAS takes care of everything, no manual trim needed.
