Took me a while, but I guess this is the solution:

import { createVfm, type Vfm } from 'vue-final-modal';

export default defineNuxtPlugin((nuxtApp) => {
    const vfm = createVfm() as Vfm;
    const { openedModals } = vfm;

    watch(openedModals, (opened) => {
        if (opened.length) {
            document.documentElement.classList.add('has-vfm');
        } else {
            document.documentElement.classList.remove('has-vfm');
        }
    });

    nuxtApp.vueApp.use(vfm);
});
