Can't turn on TSX support in my Ubuntu2204

Hello, I tried to build the FPTree project, but encountered an issue while enabling TSX support. I add "tsx=on tsx_async_abort=off" to /etc/default/grub and update grub. Then I reboot my machine, it seems like not working. My machine's CPU is Intel Xeon Gold 5320, and the Intel documentation mentions support for TSX
