Upgrade firmware version - Swith Dell S4048-ON

Hi, I have an S4048-N switch and I need to update it to the latest version available (9.14.1.14).
The problem is that my switch is on version 9.9(0.0P9) and according to the manual, I can't update directly to version 9.14. To be able to update, I first need to install version 9.10(0.0) or higher, and only then will it be possible to update to 9.14.
The even bigger problem is that, when on the product page, I don't have access to firmware 9.10 to proceed with the gradual update.
I didn't update because I'm in production and I ran into this situation.
