Modifying chris' answer I was able to come up with the following solution:

export function applyWithOverwrite(source: Source, rules: Rule[]): Rule {
  return (tree: Tree, _context: SchematicContext) => {
    const rule = mergeWith(
      apply(source, [
        ...rules,
        forEach((fileEntry) => {
          if (tree.exists(fileEntry.path)) {
            tree.overwrite(fileEntry.path, fileEntry.content);
            return null;
          }
          return fileEntry;
        }),

      ]),
    );

    return rule(tree, _context);
  };
}

Replace your usage of apply with calls to this function.

 applyWithOverwrite(url('./files/stylelint'), [
        template({
          dot: '.',
        }),
      ]),
