A possible approach could be something like this:

export class MyValidator extends AbstractValidator<MyObj> {
    constructor() {
        super();

        this.validateIfString(dto => dto.property1)
            .isNotEmpty()
            .whenDefined();

        this.validateIfString(dto => dto.property2)
            .isNotEmpty()
            .withFailureMessage(`property2 is invalid`)
            .whenDefined();

        this.validateIfNumber(dto => dto.property3)
            .isNotEqualTo(0)
            .withFailureMessage(`property3 cannot be zero`)
            .whenDefined();

        this.validateIf(dto => dto.property1 || dto.property1 || dto.property3)
            .isDefined()
            .withFailureMessage('at least one property has to be defined');
    }
}
