Inquiry on LMS/XMSS Integration into OEMiRoT for STM32U3/U5 Series

Dear ST,

 

Has LMS/XMSS-based firmware authentication been integrated into the STM32U563 SBSFU (MCUboot) example, or was the PQC library only validated independently on the STM32U563?

Is there an official LMS/XMSS-enabled Secure Boot or Secure Firmware Update example available for STM32U3 OEMiRoT, specifically STM32U385?

 

Thanks.
