Volunteer Doing vs. Volunteer To Do
Cambridge documents volunteer + to-infinitive for offering to do something and volunteer for + noun for offering oneself for a role or task. Bare “volunteer doing” is not the parallel standard complement for the offer-to-act construction.
Use “volunteer to do” when someone offers to perform an action; use “volunteer for” before a role, task or activity expressed as a noun phrase. Bare “volunteer doing” is not the parallel standard complement for the offer-to-act construction.

Quick tests
Offer-form test
Is someone offering to perform a specific action?
If yes: Use “volunteer to + verb.”
If no: If a role or task is expressed as a noun phrase, “volunteer for + noun” may fit.
Caveat: This decision concerns the offer-to-act construction; it does not claim that every nearby occurrence of “volunteer” and an -ing form is impossible.
Examples
Maya volunteered to organize the files.
The subject offers to perform the action.
Two students volunteered for the evening shift.
“For” introduces the role or assignment as a noun phrase.
