Unfortunately not, you just need more RAM or a Flash/EPROM module with the programming hardware.
Most application ROM modules were either 16K or 32K, HHP and CMT RAM memory modules were sold in 32KB steps (32/64/96/128/160KB).
The HP-71B Compendium (Part 3 or PDF) list the available options.
There is also the HP-71B MultiMod ROM Emulator card reader module that was not available when the compendium was published.
Unfortunately the FRAM module is no longer available and the RAM modules, front-port and/or card-reader port, when available, are expensive on eBay.
