To use the barrier algorithm without crossover with cplex 20.1, you can use the following options:

• set lpmethod 4 (this selects the barrier algorithm):
• set solutiontype 2 (this deactivates crossover):

The log looks like this:

You can see the barrier algorithm is indeed used. If you activate crossover, you can view some additional information:
