I needed to hack src/input/mpegts/linuxdvb/linuxdvb_adapter.c, before the DVB-C port is visible:
static dvb_fe_type_t
linux_dvb_get_type(int linux_type) {
switch (linux_type) {
case FE_QPSK:
return DVB_TYPE_C;
case FE_QAM:
return DVB_TYPE_C;
case FE_OFDM:
return DVB_TYPE_C;
case FE_ATSC:
return DVB_TYPE_ATSC;
default:
return DVB_TYPE_C;
}
}

Result:
