Adafruit Metro M4 Samd51 disabling mass storage

Hello I just bought a Adafruit Metro M4 Samd51 board. And when i connect it to my computer it acts like a USB mass storage device. I have been searching around online and i can not find a way to disable it or maybe need a different tyoe of boot loader for that. Can someone help me to figure out how i can disable this feature please?

I don't want to disable the programming i want to disable the mass storage area and i don't know how. When i uploaded a blink sketch that mass storage is still there.
