How to config power DNS to resolve both aws internal and company internal at a time?

I’ve configured PowerDNS server to check with company’s internal DNS and Pointed DHCP options of VPC to PowerDNS server address. But, I’m unable to resolve AWS internal DNS with that. Tried configuring AWS DNS server address in PowerDNS, but no use.

/etc/pdns-recursor/recursor.conf
setgid=pdns-recursor
setuid=pdns-recursor
serve-rfc1918=no
local-address=0.0.0.0
forward-zones=domainname=...;169.254.169.253
where … is company’s internal DNS and 169.254.169.253 is AWS DNS server.
