can you achieve the goal of obtaining data by utilizing certain functions of the router or connecting external devices to it? In other words, can you use these methods to replace DMA operations?Price is not an issue.

No. This fundamentally doesn't work, because a router and DMA operate on completely different levels:
A DMA card reads a computer's physical memory (RAM).
A router works at the network level, it only forwards IP packets between devices and has no access whatsoever to the RAM of a connected machine.

Through the router, you can at most see the network traffic a program actually sends over the network. That's something entirely different from memory contents: it's usually encrypted, often in a proprietary protocol, and it doesn't contain the same information that sits in RAM. A router therefore cannot replace DMA memory access in principle, the two concepts have nothing to do with each other.
