Fly Machine + XDP bpf program

I’m trying to attach a very simple bpf program to the XDP of a fly machine.
I’m using cilium/ebpf to compile, load & attach the program.
Once i attempt to attach the bpf program, I get this error
can't create link: operation not supported

Here’s a link to the bpf prog

Any help?
Machine Specs
VM size - shared-cpu-1x
Memory - 256MB
CPU cores - 1.0

I believe our current VM kernels are CONFIG_XDP_SOCKETS=n — TC BPF should work fine, but XDP probably won’t.

ah okay, thanks thomas!
