you have no say about it unless you yank the plug out of the wall or wipe the drive and install something else.
It doesn't have to be that drastic. Whitelist IP ranges you need on your Windows box at an external firewall. Do most all your browsing/networking in a VM. The Windows 10 side will never be able to phone home again. No telemetry, no forced updates, and you have reigned in the beast.
