I have a project at this moment, and I had to disable the Bluetooth of my Raspberry Pi 3 to use the AMA0
port, I mean the main UART port. At this moment I need use both ports: AMA0
and ttyS0
. Are there some form to put the ttyS0
on the GPIO again, using both UARTs at the same time?

Unless you have a compute module you are limited to a single UART.
On some Pi's (not the Pi3) you can choose to use /dev/ttyAMA0 or /dev/ttyS0 but only ONE at a time as they use the same GPIO.
