I will echo the commentary that if I am going to run one naked, it's actually going to be a CR90B.
A CR90A, naked, wants to stay at long range and evade. The problem is that your average damage output from the front arc then becomes an exepcted 1.5 before your opponent mitigates. Basically, it can lightly tickle things and that is all. It is mathematically incapable of hurting a flotilla at long range, for example, without a CF command.
So you would need objectives that reward running away and not being in a fixed place while playing a second player to get real value out of it, and the truth is that those don't exist. I think with the A, you need to be running TRC or you shouldn't take it.
On the other hand, I think the B is actually quite useful even without upgrades. It's dirt cheap (39 points, the best non-flotilla cost in the game), it hits surprisingly hard since it can reliably get close enough to double arc. It is fragile, and it will die quickly, but if you need a blocker / spare activation / extra ship it can be quite useful. With Rieekan, it becomes supremely annoying because it can become a one turn guaranteed jam of another ship.
So, to answer your question, I would run one naked without upgrades by taking that A piece of cardboard on the base and flipping it over to the B side, and playing it as a ship either destined to live (because I need something to escape) or destined to die (because it's my best option to deny a key enemy piece) and try to maximize its annoyance level.
