Possible to change when GRUB asks for passphrase?

Greetings,

Is there a way to modify when the decryption passphrase is prompted for KDE Neon in a dual boot setup? Both encrypted KDE Neon and Windows 11 are installed on separate SSDs. After POST screen, encryption password is prompted before proceeding to GRUB.

I’d like the machine to boot to GRUB and only ask for decryption passphrase for the operating system being booted into via GRUB.

Ubuntu works this way, and I don’t know how to configure this aspect of how KDE Neon handles things.
