How can i replace GRUB with the Windows 10 bootloader on UEFI?

So i recently made a dual-boot with Ubuntu unity 20.04 And Windows 10 Pro, but I noticed that the bootloader has changed to GRUB.

I have seen tutorials on this topic, but they keep mention to change some stuff on MBR to work or using EasyBCD. The thing is, I'm on UEFI with GPT and EasyBCD doesnt support some stuff when you are on UEFI.

The reason im asking this is because i installed ubuntu and (possibly grub) on my external hdd and, removing the drive wouldnt allow me to boot to any os at all.

Btw I cant enable MBR or any other form of legacy stuff anywhere, so im pretty much stuck with UEFI.
