FYI

representative office VS branch office

Did you check the site of DEPARTMENT OF COMMERCE, MOEA COMMERCE INDUSTRIAL SERVICES PORTAL? Handling of company establishment and application for change operation flow https://gcis.nat.gov.tw/mainNew/English/subclassEnAction.do?method=getFile&pk=150

Your office doesn’t need to support your ARC, so it might not be so hard to open and keep a branch or representative office of your foreign company
