I need to set tc under network manager to enable CAKE in Fedora/Red

On my test machine, I can the appropriate options with tc, but it is

immediately reset by Network Manager.
How did you set the tc options?
From the command-line, below.
I see code in
https://gitlab.freedesktop.org/NetworkManager/NetworkManager/blob/master/libnm-core/nm-setting-tc-config.c
which implements setting tc qdisc, and a brief mention in
https://developer.gnome.org/NetworkManager/stable/
However the man pages do not mention tc.
Can you provide a hint on setting, for example, /tc qdisc replace dev
enp0s25 root cake bandwidth 20mbit/ in network manager?
"cake" is currently not supported. Until that is added, the intended
solution is to use a dispatcher script. See `man NetworkManager`.
Alas, that's the first place I looked (:-()
Cake doesn't need to be supported in network manager, as I can work
around it's lack with fq_codel.
However, I do need to discover the location and notation interpreted by
nm-setting-tc-config.c
1) can you help me with that?
2) is adding (the name of) the cake qdisc on your backlog?
