Instead if redefining the default separator for all floats you can create your
own set and apply it only to formulas.

There are different separators you can set:

1. The separator between the section numbers in the prefix,

2. the separator between the prefix and the formula number and

3. the separator between the formula numbers (main and sub numbers).

\defineseparatorset[formulaprefix][][+]
\defineseparatorset[formulanumber][][-]

\setupformulas
[prefixseparatorset=formulaprefix,
numberseparatorset=formulanumber,
prefixconnector=?,
prefixsegments=1:*]
