There's actually two with English fan translation, one being a reincarnation as a spaceship's AI and another (a misunderstanding/comedy one) reincarnating as a noble ruling a poor planetary system. There's some more in Narou that I remember seeing.
Would like two know their names and look them up
That said, both your mentions gave me a weird idea.
The Protagonist is an Isekai who ends up in the body of a "War-Lover". Essentially they are a Mechanical Version or Expy of Warhammer 40000's Orks and were originally made as an army for universal/multiversal conquest, but the problem was that they were SO bloodthirsty that they ended up both murdering their creators and later on one another.
In-Spite of being AI, they are not so intelligent, or simply put even the smarter ones die due to their sheer bloodlust making them do unnecessary fights.
The Isekai-MC makes use of his intelligence, which grows over time, in order to be a "WarNode" and take control of a bunch of other "War-Lovers" who over time also gain human levels of intelligence and can do more complicated things like Martial Arts, Logistics, Repairs&Upgrades and Tactics
MC desires for his "people" to be MORE than just a race of horrible, bloodthirsty, highly sociopathic Blood Knights obsessed with showing their strength and fighting. One of the first things he does is to save an alien race a massive Alien Pirate Fleet and then make them his vassals and promise that they will be under their protection. The MC discovers that alongside his intelligence upgrades, he can give out the ability for them to feel compassion or bonds with other "War-Lovers" and even other races.
The rest of the series becomes both about constant conquest, dealing with possible betrayals, discovery, meeting "Worthy Opponents", dealing in Intergalatic/Interdimensional/Multiversal Politics and also the HORRIBLE bloodlust that comes with being a "War-Lover" as well which clashes with the desire to protect people and try making peace.
Also, by politics, I mean things like some races being aghast or extremely skeptical at the idea of smart and negotiating "War-Lovers" who may even want actual peace
