Segregating web and app activities with multiple PCs

Maybe I’m taking this too seriously, but I’ve already been segregating my activities with three different phones so I’m sort of used to doing it. Now I want to do it with PCs. At home, I already have two different ISPs due to the nature of my work so I need a fallback service for enhanced reliability so I have two different public IPs. One idea I have in mind is to install Proxmox on each of the PCs I buy. Then install the OS on each of the VMs I create. The other idea is to install the OS bare metal. To keep costs low, I’ll be buying the PCs used, but I’ll be buying new SSDs. Will this setup enhance my privacy? I’m sort of worried that using Proxmox might make things too complicated and compromise my privacy and security. I also have Mullvad. So if you guys were in my shoes, how would you set this up to enhance your privacy and make it as difficult to be tracked and profiled? I’m assuming every machine should have a different IP. If using KVMs to make it easier to switch from one PC to another, could my privacy be compromised? To be very clear, I’ll make sure Google and Meta accounts are also never used on the web browsing machine. Any time I need to sign into an account, I’ll be using a dedicated machine for it.
