Is there any way to use this plugin to lint a code base with mixed JS and TS sources for the Vue files?

Basically a follow-up to this issue typescript-eslint/typescript-eslint#1835 where the reporter was recommended to check here. I'm in the same situation where we're trying to migrate a project from JS to TS and currently there doesn't seem to be a way to enable the TS rules only for files where <script lang="ts"> is used.
