OpenWrt with BTF

I have a Raspberry Pi 4 B with OpenWRT 22.03.3, I'm trying to run some eBPF programs with BTF. But the standard build is not built with BTF enabled. So I'm trying to build openwrt with CONFIG_DEBUG_INFO_BTF=y, but I can't seem to find how or where to enable this. Can anyone help me with this please?
