You can't "lock" something that doesn't exist.

It was mentioned before: all races (with the exception of Roe and Lala), use one model, adjusted to different parameters. Look at male Mid Hyur and male Au Ra. They are very different, but they use same body model. So there is a high chance that Hrothgars use Roe's body, not unique one. Welp, miners will investigate it quite soon anyway.

Even if one model is altered to make the options we have, does not mean they don't become new models once altered.
