I have two 4090d graphics cards. Can I connect 8 monitors to form a unified desktop

windows10 x64,I have two 4090d graphics cards. Can I connect 8 monitors to form a unified desktop,please?
Iike mosaic or surround.
But does 4090d not support Mosaic? Surrond settings also seem unable to support splicing screens across these two graphics cards.
So if I want to complete screen splicing (more than 4 monitors), can’t I use a 4090d graphics card?
If it is indeed not possible to use a 4090d graphics card, may I ask which model of Quadro or Nvidia RTX series graphics card I should use to achieve the same level of performance as a 4090d for better rendering and display of 3D models?
