You can get the cal data out, but I don't think you can load the data back in.
You can use this simple shell script from my toolbox to save the configuration and calibration on the PC and restore it later on the NanoVNA. Works for -H and -H4.
I read out the binary block with configuration and calibration from the flash via dfu-tool upload and restore it via dfu-tool download.
I don't care about the internal format, just stupid bytes :)
I'm working on a straightforward python tool to parse the bin file and save the individual calibration slots under "talking" filenames, e.g. "config_10000000_20000000_101.slot" for a 101-point calibration from 10MHz to 20MHz.
With a simple "cat FILE1.slot FILE2.slot ... >my_new_config.bin" you can rearrange the data and "flash" it back to suit your needs.
