Don't put your money on it.
Nobody can tell you what's really going to happen. Only time will tell. But buying an LH ticket on a route that they declared they won't be flying indefinitely is a gamble.
From a quick look at the map, Istanbul looks like a much safer bet. Flying through Russia can also be an option. Some EU to Russia flights were cancelled due to the same crisis, but some are still flying.

At present, all EU based carriers are banned from overflying, and landing in, Belarusian airspace. Belarusian airlines are also banned from overflying, and landing in, EU airspace. Thus there are no direct flights from Minsk to anywhere in the EU.
Russia has also denied entry to an flight from Paris to Moscow, and another from Vienna to Moscow. These flights would have overflown Belarus, but Russia refused the flights' alternative route avoiding Belarus.
To get from Belarus to the EU, the most sensible (even though it's a long way around) is to travel through either Istanbul or Moscow. This assumes that there are no COVID-related restrictions on your proposed flight. Your other option is to try the land crossings, but that will need to be researched first.
