call static template method of template class with class as parameter

There is nothing wrong with static methods of template classes having (i) templates and (ii) the class itself as a parameter, is there? Consider the class

template<class Projection>
struct FrameData {
    // ...
    template <bool devPtr>
    static void allocate(FrameData<Projection> &data) {
        // ... do allocations ...
    }

}

This is declared in the header of file A. Elsewhere in the world, I have something like

template <class Projection>
void some_method(FrameData<Projection> &m_data) {
    FrameData<Projection>::allocate<true>(m_data);
}

I'm ending up with some

error: reference to overloaded function could not be resolved; did you mean to call it?

Elsewhere in this world is technically in a source file with some explicit instantiations going on at the bottom, but I put this all in one file with the same errors. Thank you for any insight, please refrain from shaming me on non-header templates. It wasn't my choice.

Is there some sort of analagous .template magic for static methods like the answer here?

Yes.

template <class Projection>
void some_method(FrameData<Projection> &m_data) {
    FrameData<Projection>::template allocate<true>(m_data);
}
