CentOS - Nov 2021 - RADVd and DHCPv6?

Hello,

these are my settings in

radvd.conf

interface br0
{
 ??????? AdvSendAdvert on;
 ? ? ??? AdvManagedFlag on;
 ??????? AdvOtherConfigFlag on;
 ??????? MinRtrAdvInterval 5;
 ??????? MaxRtrAdvInterval 15;
 ??????? route fe80::1/64
 ??????? {
 ??????????????? AdvRouteLifetime infinity;
 ??????????????? AdvRoutePreference high;
 ??????? };
};

in general I use stateful DHCPv6 (AdvManagedFlag on),
but is there a way to have some devices (Android) get their IPv6 by SLAAC?

Thanks,
Walter
