networking.enableIPv6 = false only sets the system sysctl; NetworkManager keeps re-enabling disable_ipv6=0 per-interface because connection defaults to ipv6.method = auto. The "?" icon comes back because NM's v6 connectivity probe races over a SLAAC ULA with no real upstream. Forces ipv6.method = disabled in NetworkManager's connection defaults and stops the kernel from accepting router advertisements, so v6 never gets brought up on any new or existing connection.
