To answer your question: Yes. You can easily just install Intel® Solid-State Drive Toolbox in Windows® 10 and run the firmware upgrade.
We have tested it this way and it worked just fine.
Also, there is no need to back up your files as the upgrade won't erase any data. Intel does recommend to always back up your information in order to avoid data loss.
Let us know if you encounter any issues.
