Windows on xperia 1 (snapdragon 855)?

我可以在 xperia 1 上安装 windows,因为它有用于 hdmi 输出的 usb c 3.1? 和用于存储的 sd 卡插槽

Your USB controller has nothing to do with EDK2. Most devices still have EHCI controllers (USB 2.0) that are 22 years old (2000). Even flagships like iPhone 13 Pro Max, Xiaomi 12 Pro still have EHCI. You can try porting an EDK2 yourself. For this you have to remove the XBL first. You can start by downloading your Stock ROM.
