Whether or not you're using ESXi, or want to, is an entirely different question. But "you're not able to" is simply incorrect. I virtualize several build agents and have for years with no issues.
macOS 26 is the last major version to support Intel, so once macOS 28 is latest this will probably become impossible (macOS 26 should be able to use Xcode 27, but maybe the platform removal will change this previous year's OS support from continuing).
Sure you can. And officially, too. Apple still ships a bunch of virtualization drivers in macOS itself. Have a look:
/System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/AppleVmxnet3Ethernet.kext
