is there any way to have grub use the shim loader for my windows boot manager entry instead of the normal microsoft one on my linux dual boot

As far as HackBGRT is concerned, you can select the option to install only files (without creating a new boot entry). This installs shim as /EFI/HackBGRT/loader.efi and HackBGRT as /EFI/HackBGRT/grubx64.efi.

Then you should be able to chainload with GRUB2 like this:

menuentry "Windows with HackBGRT" {
        insmod part_gpt
        insmod chain
        set root='(hd0,gpt1)'
        chainloader /EFI/HackBGRT/loader.efi
}

Refer to GRUB and/or your OS documentation for further instructions.
