Hello @IDGaleevgm01f8 ,
In Magento 2.4.0, Magento removed support for three deprecated catalog search engines: MySQL and Elasticsearch 2.x, 5.x, and 6.x. Merchants must install and configure a supported version of Elasticsearch before they upgrade to Magento 2.4. New installations require a connection to Elasticsearch to complete.
So prior installation, Elastic search should be configured on your server and should have active nodes to setup Magento.
And it's possible to install Magento on ISPmanager, please read this blog for further installation assistance :
