Professionals should be sticking to positive statements [1] though. So saying something like, the covid vaccine will give you austim I think should be grounds for losing your license.
On the other hand, saying something like, there's a high change you'll have flu like symptoms if you get the vaccine would not be grounds (the symptoms are disclosed as part of the vaccine trials).
But saying something like, I would like to try X treatment that isn't typically done but I've done it a few times recently and had good results I think should also be fine.
The law makes the claim of "contemporary scientific consensus contrary to the standard of care" which I think is a very reasonable statement. In general, you want people to recommend treatments that historically have worked for a condition. And for experimental type situations all the Licensee needs to do is to make it clear that the treatment isn't backed up by existing studies.

One thing I have observed - a lot of what people call “scientific consensus” is not the consensus of the research literature, rather it is the “consensus” of position statements put out by professional bodies. The later often lack much of the tentative and provisional nature of the former, with doubts and uncertainties being hidden rather than highlighted. While even peer-reviewed research is not immune to political pressures, these kinds of “position statements” are much more susceptible to political influence than the actual research literature is.
My second point is that professionals should already accurately tell the truth to their patients.
