customize canonical pages

Hello @efimov2025

Thank you for your message.

Please note that some options are only available when you enable the Advanced Mode in Rank Math. We give you an option to choose between the two during the setup wizard and you must have chosen to use the Easy Mode.

You can switch to the Advanced Mode from the top-right corner at WordPress Dashboard > Rank Math > Dashboard

Here is a screenshot for reference:
