Cuda issue with GTX 1080 Ti

Hi there!
I had to reboot my laptop from scratch recently, and install all the pilotes and drivers again. I’m on a Razer Blade 15" advanced 2019. I’d like to use my eGpu again, there’s an 1080 Ti, windows 11 recognizes the Gpu but there’s no CUDA linked to it. I’m working on Cinema4D + Octane and it doesn’t recognise the graphic card without the Cuda Driver.
I’ve installed the latest pilotes, both Cuda and Ndivia for all my graphic cards but still no Cuda for the 1080 Ti :(
What else should I do ?
Thanks for your help!
