How to receive both extended & standard CAN messages using enhanced FIFO in RTD?

I am configuring the RTD CAN RX enhanced FIFO. But I cannot make the CAN module to receive both extended&standard CAN messages.

The S32G2 reference manual mentioned the enhanced FIFO can receive 2 different CAN message types

But the RTD seems don't allow me to do that. It only let me to use all extended or standard filters.

The generated code cannot have num_enhanced_std_id_filters and num_enhanced_ext_id_filters non-zero at the same time.

const Flexcan_Ip_ConfigType Flexcan_aCtrlConfigPB_VS_0[4U]= { /* Can Hardware Channel FLEXCAN_0 */ { ... /* The number of standard ID filter elements */ 0U, /* The number of extended ID filter elements */ 2U,

Does the RTD support this feature? If not, what is the alternative solution to receive extended&standard messages in a single CAN module?
