Where is the network acceleration toggle?

I have the flint 1 and just enabled SQM but I read on here that disabling hardware acceleration can allow me to reach faster speeds with SQM. But I cannot find the setting. I looked under the network tab but there is no network acceleration menu. Using version 4.5.16.

Never mind - I just noticed in the docs that it says there are only a few supported models, and the Flint is not one of them

Is the network acceleration available in all network -modes?
I own two GL-SFT1200(Opal) v.4.3.11 using them as accesspoint. In this mode the option Network-acceleration is not shown.

Not sure. I have mine in router mode but I don’t see the option.
