To boot windows I pick the option "Windows boot manager (P1: Samsung SSD
860 EVO 1TB)" from the BIOS boot menu.

Grub is booted by default, if I go through manual path the option in the
menu is "P1: Samsung SSD 850 PRO 1TB"

Isn't there a labelled boot entry for GRUB/Linux in the EFI boot menu ?
Is there a line in /etc/fstab to mount the EFI partition on /boot/efi ?
Is there a GRUB instance in (/boot/efi/)EFI/* on the EFI partition ?
Is there a directory /boot/grub/x86_64-efi ?
