Command / Configure battery config fails on Linux since firmware update

Hi,

on my XPS 13 9380, command and configure 4.2 fail to set battery configs, on firmware version 0.1.3.2 and 0.1.4.0. It worked perfectly before.

sudo /opt/dell/dcc/cctk  --PrimaryBattChargeCfg=Standard

There was an error setting the option 'PrimaryBattChargeCfg'.

If SMM Security Mitigations are disabled in BIOS, I get error messages in dmesg, if enabled, nothing.

In dmesg I get:
