If you can use nextCloud at all, as a substitute for Google Drive, then Drive isn't the product you wanted in the first place.

The strength of Google Drive is in the collaborative document editing. Not the "drive" aspect of it.

Today anyway. It didn't start out like that.

As a sort of global filesystem, it fails miserably IMHO and always did. Even if it were available on Linux, I wouldn't use it for that purpose.
