You can use triqs: https://triqs.github.io/dft_tools/2.1.x/guide/conv_vasp.html

It has an interface for VASP that allows you to import the DFT interaction parameters and modify them through its DMFT solvers.

Here is a step-by-step example on how to use this program in combination with VASP to calculate the electronic structure of Ce: https://triqs.github.io/hubbardI/latest/ce.html

Thanks much Dr. Mohammad Saeed Bahramy I will try and let you know if I have any questions!
