The Mooney M20F has a fuel injection system so there is no carburetor nor
'carb heat'.

Right, I know it is fuel injected, but it is a "throttle body" type, rather
than individual injectors for each cylinder, isn't it?

It seems to me that if it is this type, a possibility of a temperature drop
from evaporating fuel could still open up an opportunity for water vapor in
the air to freeze, in the right conditions.
