Not that I'm aware of except make green plum jam.

You could try chutney - not done it, but you generally use unripe
fruit for it.

I must make some more hot japonica chutney this year, and teach my
niece how. It's for people who (like me) find most chutneys too
sweet and with no kick. Just use japonica instead of apple (it's
a lot sourer), perhaps a fraction less sugar, and chilli to taste.
