Hello,
Thank you for contacting Rank Math, and sorry for any inconvenience caused.
Some settings are only available when you have activated Advanced Mode in Rank Math.
Please enable Advanced Mode by going to the Rank Math dashboard.

Once enabled, head over to Rank Math > General Settings > Webmaster Tools.
I hope this helps. Looking forward to helping you.
