Magento 2.4.3: set product image URL from image server

I have a magento 2 website, configuration is as below:

- ngnix
- php7.4
- mariadb 10.4
- elasticsearch 7.10
- varnish 7.0
- rabbitmq 3.9

OBJECTIVE – I am looking to use products images from my other image server

I set my image server URL to magento 2 configuration –

stores > configuration > General > Web > Base URL's > Base URL for User Media Files

I set my URL and it successfully showing it in each product image.

but the issue is it is adding cache in each URL, due to which products images are not showing.

any thing is wrong in it .

Any help is appreciable, I have done all caching flushing already.

Thanks
