TWR-K70F120M Kit cpu and two UARTs

Plan to use UART with TWR-K70 Kit for application. Would prefer cpu UART0.
One UART (cpu UART2, cpu SCH signals PTE16/PTE17, ELEV pins A44/A43 via R116/R115) is routed to TWR-SER board and should be used for debug/conio purpose.
I see one other UART on cpu board tower pins: Cpu UART3, cpu SCH signals PTF8/PTF7, ELEV pins A42/A41 via R135/R134. R135 and R134 have attribut "DNP" (do not place).

1. So to get cpu UART3 Rx/Tx to work: Simply have to place these '0 ohm resistors'/wires ?

2. As PTF8/PTF7 also are connected to 'LCD_D4/LCD_D3': May still use UART3 with active LCD board mounted?

3. See Cpu UART0 (preferred) connected to cpu SCH signals PTF18/PTF17. These are connected to LCD_D14/LCD_D13. Can use them with LCD dismounted?

4. Any other suggestion for second/application UART on this kit?

Best regards, Juergen.
