Sorry to post so late -- I just discovered this Forum.
Yes, you can upgrade to the latest supported Version of the myRIO Software Toolkit, which (unfortunately) is myRIO Software Toolkit 2019. NI never issued the 2020 version, but "promised" a 2021 version "in the third or fourth quarter". Myself, I'm hoping if/when LabVIEW 2022 is released, there will be a myRIO Software Toolkit 2022 that includes the more recent FPGA compiler(s).
Do a Web search for "myRIO Software Bundle", and you should end up at an NI Site that will allow you to download the installer (via NIPM) for myRIO Software Toolkit 2019. You will use that to update the firmware on your myRIO, and then to update your LabVIEW 2019 installation to include the newer LabVIEW Real Time Module, drivers for myRIO and cRIO, and FPGA tools (if you want to write code for the myRIO's FPGA).
The myRIO to which I'm currently connected is at least eight years old, and works just fine with LabVIEW 2019.
If you have trouble, reply to this message on the Forum, and I should be able to "see" it and respond.
