I don't think that there is a global interface. You can try

\appendtoks \mathrm \to \everysetupmathematics.

In principle, we can have an interface similar to 
\setupmathematics[lcgreek=...,ucgreek=...], but the choice of keys 
requires some thought.

That is because \pmatrix uses \halign, where each cell starts a new math 
gruop. This reminds me of an old request to have support for \mhalign and 
\mvalign at the engine level.
