How can you merge two hard drives of 4TB?

Question

Yes, I know it is not recommended (but it's only temporary) and yes, I know I would lose all my data if something happens.

But, is there any way to merge my two 4TB drives into one ? I tried with the Disk Management tool on Windows but it can't do anything ; it cannot convert to Dynamic nor create Spanned or Striped Partitions.

So, is there any way for me to make these two 4TB Hard drives only one ?

*Only one as "If I connect both on my pcs, only one letter will appear, with 7.5TB of space.

Thanks in advance

I've found the answer : Storage Space on Windows does what I want, you have to select "Simple mirroring"
