Sorry, it is not clear for me what did you do and what result you got. 
There is a script that may run ifupdown hooks:
/etc/NetworkManager/dispatcher.d/01-ifupdown
I hope, dhclient settings do not conflict with NetworkManager connection 
properties.

I would not be so sure. Notice "[ifupdown] managed=false". It is better 
to have a look into "ps axuwwf" for DHCP-related stuff (dhclient, 
udhcpcd). I hope, systemd-networkd does not try to manage interfaces

     networkctl

should report "unmanaged". I assume that NetworkManager uses its 
internal DHCP client and it is OK.

Timothy, are you sure that "Pixel5" sends a DHCP lease? I have almost no 
experience with IPv6. I would try other methods for IPv6. I hope,

     nmcli connection show Pixel5

may shed more light on IPv6 configuration state. Finally, do not neglect 
"journalctl -b" messages (even though I find NetworkManager log messages 
rather noisy).
