How to implement multiple subdomains?

Question

Domain Name System

Hello, The task is to implement subdomains for the main domain 1.site.ru 2.site.ru 3.site.ru 4.site.ru and so on, there will be html pages on the subdomains.

But there is a limit on the number of subdomains "I use a beget" is it possible to do it somehow using .htaccess? or are there other options?

Here is the instruction in which exactly what you need is https://webhost1.ru/help/hosting/domain/sdomain but, according to the instructions, I even called the folders like that, just a 403 error and that's it, there is no redirect and does not open
