It is possible to disassemble the zsbl with gdb if you are using OpenOCD to connect to the board.
The initial boot process is documented in the FU740-C000 doc on the web site, see section 6 which shows the code at the reset vector address and explains how the ZSBL works. Since the reset vector and zsbl are mask roms on the FU740 chip, there is no way to change them.
