Access Raspberry Pi without SD Card & Ethernet Cable

hello! im essentially brand new to raspberry pi, my brother fell in love w them and has gifted me one to tinker w, but i am at school & didn't bring a microSD card reader, is there any way to connect to my pi without having to need any specific cables? I do have a small extra monitor that I can connect the Pi to.

The Pi is only hardware.

It needs an operating system to run, which is software.

That software needs to be read by the Pi somehow.

It's not possible to boot an OS into the Pi by using a control board connected to the GPIO headers, is it?

Could set up something like a tapper to submit Morse code for the boot up instructions.
