Raspberry pi - Scan with filter duplicates disable

[hlima]

If I run a scan on RPI4 I only get one advertising packet from my peripheral.
If I use the command
sudo hcitool -i hci0 lescan --duplicates
I get all advertisements from my perifpheral what indicates the peripheral is sending the advertisments propelry.
It looks like the blluest code is running the scan with the "filter duplicates" function on. Is there a way we can disable that filter?
The code works fine on Mac (I get all advertisements) so it seems to be platform dependent.

Thanks
