Hello,
Thank you for contacting Rank Math today.
I am sorry but we don’t have an option to change the sitemap file URL.
Please note that simply deleting the current sitemap and submitting the new URL should do the trick and this should not cause any worry.
If this is going to affect your workflow, you can keep using your current sitemap file/plugin and then disable the sitemap module in Rank Math via Rank Math > Dashboard
Looking forward to helping you. Thank you.
