Hello,
Thank you for contacting Rank Math and bringing your concern to our attention.
If you wish to remove Yoast data, please make sure first that you have successfully migrated all data from Yoast to Rank Math as removing Yoast data is a non-reversible action.
Then, I would recommend you to follow their official recommendations (as explained here: https://yoast.com/help/how-can-i-uninstall-my-plugin/#database) to remove these tables.
It is recommended to however backup your database in case they still have some dependencies just to be safe.
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
Thank you.
