Is it possible to use CODED S=2 with nRF5340 DK and nRF52840 Dongle in Zephyr/NCS?

Question

Hi everyone, I'm working on a BLE connection between an nRF5340 DK (central) and an nRF52840 Dongle (peripheral), using NCS 2.9. Both devices are configured to use the CODED PHY ( BT_CONN_LE_PHY_PARAM_CODED ), and the connection is working properly. 
 However, I noticed that the coding used is always S=8 (longer range, lower bitrate). I haven't found any way to force S=2 , which would offer faster transmission (500 kbps). From what I can tell, Zephyr only lets you request PHY_CODED , without specifying the coding scheme (S=2 vs S=8). 
 Does anyone know if it's possible to explicitly request S=2 with Zephyr/NCS on these boards? Or is this simply unsupported on the nRF5340 DK and nRF52840 Dongle with the current SDK? 
 Thanks in advance!

Hello, 
 
 You can check out my (unofficial) example here.

 Simply change BT_CONN_LE_PHY_OPT_CODED_S8 to BT_CONN_LE_PHY_OPT_CODED_S2.
