You mean there are people daily-driving KVM as a remote desktop solution? That seems like it would be remarkably painful; https://www.cnx-software.com/2024/07/08/20-nanokvm-is-a-tiny... says 100-160 ms latency, and I'm assuming that's over local network rather than trying to remote to it.
* Evading corporate IT: I do not recommend doing this.
* Normal[0] remote access to a machine: Yeah, running a remote desktop in software on the machine[1] is almost always going to be easier, cheaper, more performant, and more flexible than anything you tack on externally.
[0] Where "normal" remote access means it doesn't need to work when the machine is kernel panicked or in the firmware setup screens.
[1] The machine itself can be whatever you want. It can be an always-on desktop, but it can also be a laptop that sits in the corner and that only boots up when you poke it with a Wake-on-LAN packet, or a VM on an ESXi cluster, or a (carefully secured) Hetzner Cloud VM. That part is dealer's choice depending on your needs.
