configure dns with dhcp enabled

hi, i use wifi to access the internet. my dns provider blocks some domains. i would like to use 9.9.9.9 as dns provider. is there a way to use dhcp but not for dns information? like "use dhcp as usual but use the dns resolver x for everything"?

It would be really awesome if this could somehow be configured with GUI. But i will try it with command line, thanks! If i fail, i will ask here.

for anyone else that might encounter that:

1) list services to get the service name:
LibreELEC:~ # connmanctl services
*AO ssid1        wifi_2ccf6706c612_abc_managed_psk
   ssid2                wifi_2ccf6706c612_cde_managed_psk

2) set the dns servers on the service 
connmanctl config wifi_2ccf6706c612_abc_managed_psk --nameservers 5.1.66.255,185.150.9.255

i use those that should not filter anything for germany
