What if I don't have control over the dhcp server config, how can I
locally configure what file to load?

What if I'm running nfs, but not a tftp server?

Where does loader.efi load the kernel and modules from?  How do I
control / change that?

The configuration I prefer is that loader(8) comes from local storage
(sdcard, whatever), and it loads the kernel, the dtb, and modules, via
nfs.  I don't want uboot doing anything on the network itself.  How do
I configure that?
