Yes, nothing complicated in principle, in the settings select "Connection method" and set everything up there, the question is more different, choose good anonymous proxies, because most proxies either die in a couple of days / week, or do not provide the level of anonymity that they declare, I personally use a proxy with proxys.io, not only for Telegram, but also for work (SMM), for six months of cooperation they have never failed, because of anonymity, everything is chic, so you can use it, the price tag is certainly not from cheap, but it's better not to skimp, I'll tell you, you can't restore your nerves and time for any money!
The easiest way, which, moreover, unblocks other sites.
Download Orbot in the playmarket, run it in VPN mode, specify in Orbot settings that Telegram works through it.
As a result, everything is proxied through Tor.
Get a paid or free proxy (I had a free proxy for max 2 days, so I switched to a paid one). We need a socks5 proxy.
Under the PC in the telegram, go to Settings, Privacy and Security, Connection type, Use Proxy, enter sever, port, username, password.
Under the phone in the telegram, go to Settings, Data and Storage, Connection type, Use Proxy, enter sever, port, username, password.
Where to get a paid proxy:
http://proxy.oxilor.com (I took it here, I sit on their proxy for about a week, the flight is still normal)
1) Get yourself a VPS on DigitalOcean (the distribution is better NOT ubuntu, because there are problems during installation)
2) https://github.com/Lozy/danted dante through this script
3) Add a user
4) Set the proxy address in the telegram settings

There we turn on "VPN mode" and, by poking the gear, put a check mark next to the telegram. We turn on, wait for a bit. Done, now you have telegrams via Tor, and even without brakes.
When switching from a mobile network to wifi and vice versa, there may be problems with the connection in the TG, but this is literally 30 seconds.
Go to tproxyt.tk, then click "MTProto" or "SOCKS5", depending on which proxy you want to connect, and then click Enable in the application on your computer or smartphone. Done. You can also take a proxy directly from the bot https://t.me/tproxies_bot or on the channel https://t.me/fproxyf
Who used whose service for selling proxies and where they did not cheat. Don't want to waste your money
