Yes, you can use TWRP to flash ROM, there lots KNOX-free ROM you can use without flashing bootloader.

Toy dint bend to flash modem or bootloader they are the oart of rom but once you updated to 4.4.x you can't downgrade and 4.4.2 has camera bug draining battery by using all cores Samsung is currently fixing this issue in coming update 4.4.3...
