Hi, I found the correct configuration file and were able to fix this error:
warning: (ANDROID_DEFAULT_SETTING) selects NETFILTER_XT_MATCH_QTAGUID which has unmet direct dependencies (NET && INET && NETFILTER && NETFILTER_XTABLES && NETFILTER_XT_MATCH_SOCKET && NETFILTER_XT_MATCH_OWNER=n)
Unfortunately, the "make halium-boot" command ends with another error.

Does anyone know what to change so I can continue? 😉
