No, the Vera Rubin Observatory is on Cerro Pachón (https://en.wikipedia.org/wiki/Vera_C._Rubin_Observatory) rather than Cerro Paranal (https://en.wikipedia.org/wiki/Very_Large_Telescope), the maps on the right hand side show the difference (~6° latitude). Similarly I wouldn't expect https://en.wikipedia.org/wiki/La_Silla_Observatory to be affected, but https://en.wikipedia.org/wiki/Extremely_Large_Telescope would be I expect (noting that I haven't seen anything beyond the ESO press release).
