Well you can modify a reg , delete a dll and many other methods to bypass tpm without a special licensing of ltsc
Only actual positive ltsc has that it's the Microsoft approved way of making usable windows for low end systems and that it has more promised security updates (other PCs will have to upgrade to windows 12 to still get security updates once this mess comes back with a new version)
Basically a better ltsc is Linux as it has longer support then any ltsc license of windows and it doesn't have to promise updates you or forcing you to pay for licensing
And since Linux is just a kernel it can be lighter then ltsc unless you choose a heavy distribution that includes the Linux kernel
