Hardware auto-detection incorrectly identifies simplex MMDVM_HS hat as duplex, Duplex -> Simplex setting does not persist across reboots

[laterbreh]

Description

Pi-Star OS auto-detects my simplex MMDVM hotspot board as a duplex hat and forces Duplex=1 in the MMDVMHost configuration at every boot. I have a simplex board (STM32-DVM / MMDVM_HS - Raspberry Pi Hat GPIO), but the system incorrectly identifies it as duplex.

When I manually change Duplex=0 through the dashboard config editor, the hotspot works perfectly. However, after every reboot, the setting reverts to Duplex=1, making the hotspot non-functional until I manually edit it again.
Steps to Reproduce

 Install Pi-Star OS on Raspberry Pi Zero 2W with simplex MMDVM_HS hat
 Boot the system
 Navigate to Dashboard → Config Editor → MMDVMHost
 Change Duplex=1 to Duplex=0
 Save changes
 Reboot the hotspot
 Check /etc/mmdvmhost/MMDVMHost.ini or /data/etc/mmdvmhost/MMDVMHost.ini

Expected Result: Duplex=0 persists after reboot

Actual Result: Duplex=1 is restored automatically

Thank you for reporting this, I'll check it out, this isn't really even an alpha release yet (you'll notice there has been no mention of it anywhere yet) so there will be bugs.
