Is it possible to disable an OTF Stylistic Set defined in a paragraph style?

I have a paragraph style with an OTF Stylistic Set enabled.

When creating a character style, there is no option to disable this Stylistic Set — or to specify that no Stylistic Set should be used at all.

The font I’m using already uses all 20 Stylistic Sets, so selecting a different, unused set is not an option.

Can anyone help, please?
