Can you please add this cover to my book Blooms of Love

We cannot add a further cover to a listing. If the existing image is a placeholder and has not been used for anything, including ARCs, we can replace it with a final cover but need an acceptable source as outlined at https://help.goodreads.com/s/article/...

Existing cover I used for ARC and also for promotion. And I have communicated the change to my ARC team. . So can cover be changed after book is out on Amazon?

As the cover has been used it should not be changed.
If the ISBN remains the same add the ISBN to existing edition and then create an alternate cover edition, if the ISBN changes add a new edition.
