Is there a way to exclude IPs from the DHCP Pool?

I'm afraid you are right.
On this router, you can only enable or disable DHCP in general, but not set the range used for DHCP.

Sorry to be the bearer of bad news...

You could try to set your static IP's in the upper range (192.168.2.254 and down) because DHCP usually starts at the bottom range (192.168.2.2 and up). I know this is not an ideal solution, but it might work for you depending on the number of clients you have.

If you have any more questions, just come back here and leave a comment - I'm happy to help.
