Are you viewing that listing via a browser or the Play Store app? It looks like the Play Store app, but I'm a bit surprised if you can see it at all in that case, since that normally only shows apps that it thinks are compatible with the device (i.e. if you look for an app that isn't compatible you usually get no results at all).
Not knowing why it thinks it's incompatible it's impossible to say for sure whether there is anything you can do, but the answer is "probably not". It shouldn't be the android version (I've checked, and the app says it supports Android 8 and up), but that doesn't tell us what is wrong. You haven't rooted the phone or otherwise modified the system software? That will generally stop banking apps working, though I'd usually expect you to discover that when you tried to run it rather than when you tried to install it. If you have though you could try reflashing the phone completely back to stock firmware and see whether that solves it (at the price of giving up root, custom recovery, and any app that required root).
Otherwise the best I can suggest is that you contact the developer and see whether they have any ideas. It could be a mistake or oversight on their part, e.g. they just left your model off some list, in which case they would be able to fix it. But I'm not optimistic.
