Can't find something in menuconfig

I need to include the components mentioned in "https://github.com/daeuniverse/dae/blob/main/docs/en/README.md" when building the OpenWrt firmware (this software needs to use eBPF). but i can't find them in menuconfig

You need to use make kernel_menuconfig. The symbols mentioned in the readme are kernel settings while OpenWrt buildroot make menuconfig refers to package and feature selection.
