Does tensorrt10.8 support pointwise op between matmul and softmax when using fused mha

In tensorrt 10.8 release note, Release Notes — NVIDIA TensorRT Documentation.
In Limitations, there is a description

but the subsequent Best Practices section contains the following description:

It seems that these two descriptions are conflicting. So, does TensorRT 10.8 support inserting pointwise operations between matmul and softmax when using fp8?
