5. DNA manipulation

Yes, the very method used by DeVoe had been done to nullify Caitlin’s powers of cryokinesis and her Killer Frost persona. Although the metahuman individual known as Matthew Kim (Leonardo Nam) was the key to beating DeVoe, however, it is debated that Kim had died off-screen as DeVoe managed to display the ability to dissolve the bonds of DNA from a subject and transfer a piece of that DNA to others with physical contact.

The side-effect being transferring metahuman abilities from one person to another. While Kim may not be alive, culturing his cells in such a way so as to reverse–engineer a cure with science. This method is genetic engineering and the technique can be used to nullify DeVoe’s multiple abilities, which may be the answer.

However, genetics can be complicated and not many members on Team Flash have experience in that field, except perhaps Caitlin. She might be able to create such a treatment, as she is a bio-engineer with two doctorates and a Ph.D. She was able to assist in making a cure for the drug Mirakuru with Cisco Ramon (Carlos Valdes) and the latter four versions of the speed–enhancing drug Velocity. Although it might be plausible for Caitlin to create some kind of treatment to suppress or permanently inhibit DeVoe from gaining access to his abilities, but the downside is getting close enough to stop DeVoe.

Even if the cure is deployed by a handgun or canister, DeVoe will be to read the minds of the team and can now not be easily pounced upon after he acquired Gauss’ ability to create portals into pocket dimensions.
