According to https://www.wood-database.com/rubberwood/ it’s in a range with walnut or poplar - so look on the community for posts about engraving those 
If you have a range you want to try, start with the lightest one (lower power/higher speed) since you can always make it darker, but not so much lighter
Also keep in mind engravings will lighten up after you clean them, and with a cutting board you’re going to definitely want to scrub that out
