Everything you see on that page is completely worthless on a router connected to the internet. They just want to make it look complicated so people think it actually does something. Anything related to DSCP or precedence is removed by the ISP.
You have little options if your router does not support it, you have to buy one that does.
Be aware a router has a extremely small cpu so even fairly advanced QoS is limited in its abilities. Saying "bandwidth control of users" is way to general, You might get some ability to limit by ip or mac address. To really do advanced stuff you need a device like a pc that has powerful cpu.
