Can I use PXE without DHCP by just manually specifying a static IP?

I want to try doing a PXE install for the first time. Every single tutorial I've read seem to indicate it requires a DHCP server configured to point to the TFTP server with the boot image. I don't understand why DHCP should be required though, isn't it possible to just manually configure computer's IP and network settings, and manually specify the IP where the TFTP server is located? If not, is there any particular reason why you wouldn't be allowed to do this, or given a simple prompt in the pxe menu asking to manually specify the network path?
