Yes. When you install Linux it will auto detect the Windows EFI partition and put boot stuff there by default, but then windows comes along and will randomly trash that setup. So during install don't go with the suggested option, instead use the partitioning tool to creat another small EFI boot partition elswhere on disk, leaving Windows EFI and OS paetitions as is. Also create your root and home partition(s). Install to those partitions, then Linux should prompt for Probe Foreign OS and add a chainloader entry to your grub menu. This entry, when selected, points grub to windows EFI partition ID and hands off the boot process to Windows. Windows is unaware it has been chainloaded. As long as you set BIOS to load directly from the LINUX EFI entry then you will boot to Grub with Linux/Windows Dual option...But technically it is not a true Dual Boot, it is a sequential boot I guess. I have had this for 7 years on same install and boot between W10 and Linux daily. Windows has never touched my Linux EFI.
