eGPU, nvidia RTX 4090, Linux (Ubuntu), laptop with existing nvidia GPU


I want to buy an external GPU (eGPU) for a laptop running Linux (ubuntu) and already has one nvidia GPU (NVIDIA GeForce RTX 3080 Ti Laptop GPU). I want to use both GPUs to train AI models developed in pytorch. The laptop has Thunderbolt 4 Could you propose a suitable eGPU for this case (e.g. AORUS RTX 3080 Ti GAMING BOX, or, razer core x chroma external graphics enclosure with nvidia RTX 4090) ?
