Is NVIDIA SLI (Scalable Link Interface) used in Deep Learning?

No.

NVIDIA SLI is used for distributing graphics rasterization across multiple GPUs. SLI cannot be used to achieve performance gains in Machine Learning / Deep Learning applications. All machine learning libraries (e.g. TensorFlow, PyTorch, and Caffe) interface with the GPU through CUDA, which has no concept of SLI.
