OSD and Video Transmitter tabs missing in RC configurator versions

[ilicmiljan]

Describe the bug

When using the latest release candidate Betaflight configurator versions with Betaflight 4.5.0 firmware, the OSD and Video Transmitter tabs are missing; therefore, configuring the OSD layout is not possible.

Additionally, when inspecting the Configuration tab, the OSD is not shown as an available feature and cannot be toggled, even though the CLI config and running status command show the OSD as enabled.

status command output:

When using Betaflight configurator 10.10.0, the issue is not present, and configuration tabs are shown and working correctly.

OSD is feeding the correct data to the VTX, and everything except the missing configuration tabs is working correctly.

The hardware used is Pavo 20 Pro (F4 2-3S 20A AIO FC V1) with the DJI O4 Pro Air Unit.

To Reproduce

• Open Betaflight configurator 2025.12.0-RC2 and connect to the flight controller running Betaflight 4.5.0.
• Even though VTX is connected and supports OSD, the OSD and Video Transmitter tabs are missing from the sidebar.

Expected behavior

• OSD and Video Transmitter tabs should be present as on the Betalfight configurator 10.10.0.

I took a look at the code, and the problem seems to have been introduced with #4526.

Since the Pavo20 Pro firmware running Betaflight 4.5.0 doesn't set VTX or OSD in the build options, there are no VTX and OSD tabs in the configurator for this model.

I believe we should keep backwards compatibility for changes like this, as it probably affects many users who are running firmware built before this change.
