404 error page modify

I’d like to modify page 404 of Graffana, can I know how?

I need to erase the 404 phrase on the page, and correct the contents

I’m using an image in dockerhub v.9.4.2

Thanks and regards

Welcome

By the use of the word correct it implies something is wrong. Can you share what you see in that page that is wrong and you want to correct?

I wanna erase rad box

Thanks
