I am looking for the thermodynamics of the cosmological black hole in scalar-tensor-vector gravity theories. I know how should I write and find the thermodynamical quantities and equations for such a black hole, but I do not know that can I use the Bekenstein-Hawking area law or in this framework, I should find a modified version of it. I looked for it in literature and found out that some authors have said that in this framework, we should find a modified version of this law, and an author has said that we should use the ordinary form of the law. So, what should I do?
There are modifications and how to compute the effects of the additional scalar and vector fields, in certain circumstances, is known. Examples of such calculations may be found here: Article Area law corrections from state counting and supergravity
and/or here: Thesis Quantum Black Hole Entropy and Localization in Supergravity
for instance.The Bekenstein-Hawking area law is an asymptotic result.
No answer, but another question: What happens with the exergy in a black hole?

Our universe building block is a Quantum phenomenon, therefore everything as far as Mass, Energy, and Force must have quantum origin.
One thing for sure this universe with billions of galaxies did not created by four dumb forces and put all these galaxies in a right manner.
We must give our universe credit, and see it as a complete well organized entity that work under its own law that we do not know.
Here two unprecedented article that describe GRAVITY IS INTERNAL, AND HOW QUANTUM UNIVERSE WORKS.
Article Gravity is an Internal Force
Article How the Quantum Universe Works
