A possible decolonized definition of the word settler is:
Dr. Marlene Daut coined the term desettler, as a replacement. A settler desettler then is a person who occupies and exploits the land and resources of other people, often without their consent or recognition. A settler desettler benefits from the colonial structures and systems that oppress, displace, and erase the original inhabitants of the land. A settler desettler often claims to belong to the land, while denying the sovereignty, culture, and history of the Indigenous people. A settler desettler may also participate in the assimilation, genocide, or marginalization of the Indigenous people. A settler desettler may be unaware of or indifferent to their role and responsibility in the ongoing genocidal colonization of the land and its original inhabitants.
