How to merge 2 business profiles together?

There was a "Dental Pratice A" that was led by "Dentist A". It had a google business profile with like 5 reviews. Some years ago, "Dentist A" sold its "Dental Practice A" to Dentist B. Dentist B is the owner of it now (lets call the practice now "Dental Practice B"), it got renamed, new branding, new website, new practice basically, but still in the same address. A new google business profile got created for "Dental Practice B" under the same address which until today is well optimized and has many reviews. "Dentist A" is continuing working as an employee in that new practice.

I think it's harmful that the old google business profile of "Dental Practice A" is still existing under the same address as "Dental Practice B".

Is it possible to get the business profile of "Dental Practice A" either fully deleted, or absorbed/merged with the business profile of "Dental Practice B" (which has a lot of reviews)?

If so, What would be the right/best approach to do so?
