There seem to be more options for the full holders with pads than just the pads... I think you need M737 canto pads, someone else can hopefully confirm
The all in one pads or pad holders should have threads like this for V brakes.
The Deore XT pad holders in your photo are from the Deore XT M737 cantilever brakes and need to be clamped.
Found another V brake pad where you change the pad so basically this is what you need, pull the pin what's circled out and you slide the cartridge pad out and replace then put the pin back in.
