Can FlexComm0 be set to UART_RXD and UART_TXD during ISP API at boot and also function as the ETM TRACE data pins when debugging?  If NOT what are my options if I must have both?

I am designing the HW for a new product using the LPC54606J512BD100 as the real-time MCU.  I am running into an issue that I hope you can help me with.  I must have the method for ISP API set as USART which when I read the chapter in the User Guide on the boot process explains that it must be Flexcomm Interface 0 and specifically PIO0_29 and PIO0_30 must be USART_RXD and USART_TXD, respectively.  I also have a requirement to rout out the ETM TRACE pins for firmware debug.  The problem is that the assigned TRACEDATA[1] and TRACEDATA[2] pins are the same pins as the ISP UART RXD and TXD pins.
