Can the automatic generation of GPOS by fontmake be skipped in the builder?

For the UFOs/Designspace projects that I would like make variable fonts from the UFOs contains all the needed GPOS (and GSUB) information in `features.fea`. So I don't need, and don't want, GPOS generated automatically from anchors and/or kerning information.

It looks like the default recipe (`googlefonts`) used by the builder [always calls fontmake](https://github.com/googlefonts/gftools/blob/dd68ad01f22ea44a5d8f80523ecf8a2db32b7a12/Lib/gftools/builder/recipeproviders/googlefonts.py#L219) with `--filter ...` thus enabling the automatic GPOS generation. Is there a way to call fontmake with `--feature-writer None` instead?

I guess I could create my own recipe but having an option would be much easier.
