One or more of the system checks did not pass, with the following errors ...
Host CUDA Environment: (Unable to execute the nvcc command. Check your CUDA SDK installation.)
Code Generation: (Test GPU code generation failed with the following error 'emlc:compilationError'.)
Compatible GPU: (A valid GPU device not found on the host system. Execution of the generated GPU MEX will not
be available.)

Seems pretty clear from the very first message:
Warning: Selected MEX compiler 'MinGW64 Compiler (C++)' is not supported for GPU code generation. Refer to the
GPU Coder documentation for a list of supported GPU MEX compilers.

You need Visual Studio to compile for GPU Coder

I installed Visual studios 2019 and I am getting the error
Error using dlquantization.instrument
The value of 'executionEnvironment' is invalid. No GPU available. dlquantizer requires a GPU machine to quantize a network object.
Error in dlquantizer/calibrate (line 25)
results = dlquantization.instrument(obj.NetworkObject, p.Results.data, obj.DLAccelData, 'BatchSize', p.Results.batchSize,
'MiniBatchSize', p.Results.miniBatchSize, 'ExecutionEnvironment', obj.ExecutionEnvironment);

ikeuwanuakwa : do you have a supported NVIDIA GPU ? The supported execution environments for that function are only GPU or FPGA.

First download visuaal studio 2019 with sdk applications and write mex -setup to command window and then choose vs 2019 and c++.

I had similar problem.
Run gpuDevice from terminal
It poped an error that my nvidia driver is not supported and I have to update it first.
