Firmware upgrade for Linux user

Two months ago I bought and installed a SanDisk Ultra 3D 500 GB SATA3 disk for my new laptop. I have no problems, but I want to know how can I do a firmware upgrade on this disk (when needed) since I am not using Windows. I have only Ubuntu 19.04 installed on my laptop.

Questions:

  1. What is the current latest available firmware for this disk? My system reports X61170RL as the installed firmware on this disk. Is it the latest? I haven’t found any information about the latest firmware of this disk on sandisk.com website.

  2. Is it possible to do an update on a system which does not run Windows? How?
