Hi there and welcome to the forum!
Check-out the following link, it's a distance learning course provided by a FTO in Switzerland. No personal appearance and no classroom time required, only an ICAO CPL/IR needed. But for taking the exams you must travel to Switzerland, of course.
But be aware, don't underestimate the effort and time you must invest in order to prepare and pass the exams, it can and will be frustrating at times. Keeping up the motivation is also difficult, especially as a lone worrier. Once the exams are passed, the theory credit is only valid for 36 month in which the IR piratical test must be passed, otherwise the credit becomes invalid and all 14 exams must be re-taken.
But let me tell you, once the theoretical exams are out of the way, the flying part (IR/CPL checkride) is not a big thing, especially for someone who already holds an ICAO CPL/IR. This can be done in a week and for little money, for instance in Poland.
