Is it possible to install Ubuntu on an external SSD on the 2019 16 inch MacBook Pro?

I'm considering buying the 16 inch 2019 MacBook Pro because I need a powerful x86 machine that can run macOS, but I would also be interested in running other operating systems on this computer. I know that the T2 chip is tied to the SSD, and I was wondering if the following configuration is possible, and how I would go along doing it: - 2 partitions on the Apple SSD, one running Catalina, and one running Windows 10 through Bootcamp - 1 external SSD with 2 partitions, one with Big Sur, and one with Ubuntu If this is possible, how would I do this, and what problems would I face (WiFi, audio, etc)? If this isn't possible, what would I need to do to be able to run these 4 operating systems on this machine, or what other powerful x86 Macs would you recommend? Edit: I don't want to run virtual machines because graphics performance is bad when the VM doesn't have access to the GPU, and graphics are one of the main reasons I would want to upgrade to the 16 inch. I also don't want to spend money on VMware and install it on my Bootcamp partition, just to find out GPU passthrough doesn't deliver the level of performance I would want.
