yeah Thanks guys I found the solution it is very easy . Use Contabo Object Storage with NodeJS - DEV Community . using this tutorial and I used the official aws provider upload by strapi team just changed the plugin.js files added endpoint and s3endpointbucket and it worked .
const s3 = new AWS.S3({
endpoint: `contabo_storage_bucket_url`, // e.g. https://eu2.contabostorage.com/bucketname
accessKeyId: "your_access_key_here",
secretAccessKey: "your_secret_key_here",
s3BucketEndpoint: true,
});
