Would you mind providing some useful information about the task?
Like which color do you want to replace, how many and which spot colors will be used …?

So I assume you want to use two spot colors?
What print process and how opaque will the used colors be?

Yes, two spot colours and I would like the opacity to be full, so as much of the colour is replicated.
Print process is either primary colours or pantone colours.

You don’t seem to understand the terminology.
What print process: offset, gravure, flexo, …?
And as for the opacity that depends in part on the process and you best ask your printer about it.
If the colours are opaque one may not have to knock out the red under the dark blue, if the colours are translucent one may have to.

Well, then it may be necessary to knock out the blue.
Could you post screenshots of the Channels?

You need to create a clean greyscale representation eitehr with channel matzh operations orf selections, then assign it to spot channel a, the inverted mask to spot channel b.

I know how to do the greyscale part, but what do you mean by assign a spot channel? and channel match operations?
