Based on the examples, I created the following REST endpoints in the Apache Camel Spring Boot project and published the OpenAPI specification:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns=";
       xmlns:xsi=";
       xsi:schemaLocation="
        .xsd
        .xsd">

    <camelContext xmlns=";>

        <restConfiguration component="servlet" apiContextPath="/api-docs">
        </restConfiguration>

        <rest path="/say">
            <get path="/hello">
                <to uri="direct:hello"/>
            </get>
            <get path="/bye" consumes="application/json">
                <to uri="direct:bye"/>
            </get>
            <post path="/bye">
                <to uri="mock:update"/>
            </post>
        </rest>
    </camelContext>

</beans>

Currently, when I access the following URL: /api/api-docs, I receive the following response:

"openapi" : "3.0.0"

From which it is clear that the OpenAPI specification is being generated in version 3.0

I am using Apache Camel 4.9.0-SNAPSHOT.

Is it possible to configure Camel to generate an OpenAPI specification in version 2.0?
