you can create the complete subnet for DHCP and exclude the existing ip's being used.
Start Ip 192.168.200.1
End Ip 192.168.200.255

exclude from DHCP scope ip from
Start Ip 192.168.200.1
End Ip 192.168.200.64

But this both are different Site
And when i try to Add Exclusion
such as
192.168.200.64
192.168.200.126
but when i try to do that
i got error Ip Address range is not a subset of the overall range

So just to confirm.
you have DHCP scope from 192.168.200.1 to 192.168.200.254

then to exclude use below steps
1.Click Address Pool. Right-click Address Pool, and then click New Exclusion Range. The Add Exclusion dialog box opens.

2.In Add Exclusion, in Start IP Address, type the IP address that is the first IP address in the exclusion range.

3.In Add Exclusion, in End IP Address, type the IP address that is the last IP address in the exclusion range, and then click Add.
