Enabling NET_DROP_MONITOR

I need to configure the kernel with NET_DROP_MONITOR=Y in order to get DropWatch working. If I run make kernel_menuconfig I am not able to select this option. I'm trying to build an image for the mt7621 target with OpenWRT 19.07.5.

The search in menuconfig displays:
Depends on: NET [=y] && INET [=y] && TRACEPOINTS [=n]

Does it mean I have to enable TRACEPOINTS first? I have no clue how to do that. Does anyone have a hint for me?

also stuck on this; did you figure it out?
