I am from Austria also tinking about ordering eg. at Amazon.it to have 30 days trial (cant be ordered in Germany from Austria right now) ...
Is it ok to flash an Austian Version e.g. CSC: T705ATO1ANF1
1 will knox be triggered ?
2 is there any difference regarding GSM/LTE frequency bands or do all european devices have the same circuit boards ? One can look this up e.g. with myphoneexplorer (\System\build.prop Austria: ro.product.board=universal5420)
