I wonder if I can rewrite the DNA’s router ROM with Elisa’s version.
Short answer: No, you cannot.
Long answer: If you are a competent hacker and don’t mind bit banging jtag ports or desoldering flash chips, then maybe. However, as you cannot download the firmware anywhere, you will still need an Elisa B818-263 to extract the Elisa firmware from.

PS: Even I subscribed for Elisa XL - 600MBs, I hardly get ~70MBs (in the center of Helsinki, but also in Espoo). Could this be because of DNA’s ROM?
Possibly. 4G CA and 5G have a lot of operator dependent incompatibilities. A device branded by another operator might work with 4G without carrier aggregation and fail completely with 5G.
