Enable rumble at pairing with genuine PS3 controller?

[Epg]

Hello,
I have Retropie installed on top of OSMC on my Rpi 3 and everything works fine.

Now, I have a Rpi 4 to play with, so I have just done a fresh OSMC installation and then I've installed Retropie via script. I am very satisfied because Retropie seems more responsive on the Rpi4 and games work better so I gain parity features except for the rumble on pairing feature for my PS3 controllers.

So the question is: how to enable rumble for PS3 controller at pairing / power off of the PS3 controllers?

Searching the forum I've found this thread: https://retropie.org.uk/forum/topic/12909/disable-ps3-controller-rumble-while-pairing that suggests to edit the /var/lib/sixad/profiles/default file, but in my new Retropie installation I don't have sixad installed and reading further the forum I discovered that this daemon is now not required. I fact, In Retropie Setup I have only sixaxis installed (from src) and, after configuration/pairing, my Ps3 controllers work fine.

My setup:
Raspeberry pi 4 with 4 GB RAM
Genuine Rpi USV-C Power Supply
OS: OSMC (uname -a: Linux osmc 5.15.92-1-osmc #1 SMP PREEMPT Tue Jul 25 00:03:42 UTC 2023 aarch64 GNU/Linux)
Retropie 4.8.9 installed via retrOSMCmk2 script3
Controllers: genuine Sony PS3 Sixaxis 3 Dual Shock

Thank you.
