I'm working with an Excel file containing 1,000,000 words in Trados and need to lock repeated segments.

I think your file is simply too large for Trados.  Maybe split the Excel anyway, but use the "Export frequent segments" option to create a file that contains the segments you would lock.  Then create a TM from these segments, pre-translate the project against this TM only, then use the SDLXLIFF Toolkit to lock all the translated segments.  You can do this across multiple files so that could work.  A bit of a pain, but your file is really too large:

Hello Paul,

Will we have an adaptation plan for large files?
Because we will probably have some large files to translate in the future
