In our network settings, a REST request requires OAuth Token as a URL parameter (as access_token) and additional Basic Auth data in Authorization Header. Postman does not allow setting the Authorization header, after configuring OAuth 2.0 (in the Auth section).
Is it possible to change this behavior?

You may need to do this as a pre-request script instead of using the in-built authorization.
It gives you a bit more control over the authentication.
The following is an example of authenticating with Microsoft that you can extend to include the headers that you need. It only gets a new token if it thinks the current one has expired.
pm.test("Check for collectionVariables", function () {
let vars = ['clientId', 'clientSecret', 'tenantId', 'username', 'password', 'scope'];
vars.forEach(function (item, index, array) {
console.log(item, index);
pm.expect(pm.collectionVariables.get(item), item + " variable not set").to.not.be.undefined;
pm.expect(pm.collectionVariables.get(item), item + " variable not set").to.not.be.empty;
});
if (!pm.collectionVariables.get("bearerToken") || Date.now() > new Date(pm.collectionVariables.get("bearerTokenExpiresOn") * 1000)) {
pm.sendRequest({
url: 'https://login.microsoftonline.com/' + pm.collectionVariables.get("tenantId") + '/oauth2/v2.0/token',
method: 'POST',
header: 'Content-Type: application/x-www-form-urlencoded',
body: {
mode: 'urlencoded',
urlencoded: [
{ key: "client_id", value: pm.collectionVariables.get("clientId"), disabled: false },
{ key: "scope", value: pm.collectionVariables.get("scope"), disabled: false },
{ key: "username", value: pm.collectionVariables.get("username"), disabled: false },
{ key: "password", value: pm.collectionVariables.get("password"), disabled: false },
{ key: "client_secret", value: pm.collectionVariables.get("clientSecret"), disabled: false },
{ key: "grant_type", value: "password", disabled: false },
]
}
}, function (err, res) {
if (err) {
console.log(err);
} else {
pm.test("Status code is 200", () => {
pm.expect(res).to.have.status(200);
});
let resJson = res.json();
pm.collectionVariables.set("bearerTokenExpiresOn", resJson.expires_in);
pm.collectionVariables.set("bearerToken", resJson.id_token);
}
});
}
});
