Lavender and mint are good choices to cover the smell. You can grow them around your plants and they give off a lot of smell. For drying best options would be a Carbon filter and a closed off dryroom. But Maybe if you hang some lavender to dry with it, it will cover it up as well? Might be a bit late to plant it since you're almost ready for harvest, but there must be plants that are already pretty grown up you can buy and use in time
