Good morning
I do not recommend disabling IPv6, we cannot guarantee full functionality if you do. There is also the future inevitability of Internet brownouts once all IPv4 addresses are assigned. If you do not have IPv6 available when this happens, you won't be able to connect to the Internet until an IP address lease is freed up.
There's nothing wrong with you testing this out to see if it works for your current network setup, however! I just want you to be aware of the downsides.
