Do you meam TWRP via SP Flash Tool?
It's better to do it with fastboot and I'm not sure if SP flash tool will even work however if you want to try, you could do this..
*I am assuming you know how to use SP flash tool and have proper drivers installed*
Get the scatter file for your firmware and then copy it to the folder in which you have your TWRP IMAGE stored. Now rename the twrp image to recovery.img.
Open SP Flash tool and then load your scatter file and let it load. Once done, uncheck everything except recovery partition and then click on download and then connect your phone with USB cable and let it flash. There should be a green tick if it finished correctly now try booting recovery mode by pressing power+vol. Up at the same time.
If the process was successful you should boot into TWRP now.
NOTE : I HAVE NOT TESTED THIS METHOD MYSELF AND CAN'T CONFIRM THAT IT WORKS OR NOT. IF YOU BRICK YOUR PHONE OR ANYTHING HAPPENS TO IT, I AM NOT RESPONSIBLE FOR IT. YOU AND ONLY YOU ARE RESPONSIBLE FOR YOUR ACTONS
