You can do that just in case but I don't think it will be necessary. I am
using Arch for years now in 3 different UEFI computers with Windows 10.
Just follow the installation guide and boot loader wiki page. Just like
Jason and Artur linked, wiki warns you for possible problems before you
face them and suggests fixes.
In case you wonder, I am using systemd-boot with (almost) default configs.
Never used GRUB with Arch but it doesn't cause any problems on other Linux
distros (at least for me) with Windows 10 dual boot so it is a safe bet too.
