Compute shader texture input

Hello everyone,
I found myself with new questions on Compute Shaders.

I am using SRP as a hook to write a render pipeline from scratch.
I am experimenting with writing compute shaders, and found a net difference between the command buffer API and the Compute Shader one.

1) In the command buffer API, you can set textures on a compute shader but ONLY with a RenderTargetIdentifier.
2) In the compute shader API, you can set texture but ONLY with the Texture class.

I wanted to use Command Buffers everywhere to have a more homogeneous code, but now I am not sure the best way to proceed.

If for example, I want to write a SSAO compute shader, I would have both a Noise texture (an asset, loaded from disk) and at least the depth buffer to read.

What is the best way to achieve this ?
Tried searching around but no luck.

Thank you a lot!
