they are not incompatible. You can have secure boot and FDE for both linux and windows on the same system.
Just put linux's boot drive on a removable USB that has boot priority over the builtin drive. Then configure UEFI secure boot so that it works for both windows and your custom keys.
This setup has the added benefit of making it so that windows can't overwrite your linux boot drive, but from linux you can still access your disk from disklocker
