Plural or Singular “Kol Nidrei”

Shalom aleichem Rabbi Lauffer. Thank you for answering my last question. In the sefer “Guidelines” to the Yomim Nora’im, they write that a yachid can say Kol Nidrei as long as he says the future tense version.

Would he be able to say the Kol Nidrei prayer exactly as the Siddur has it, even though the Siddur says “that we will vow…etc” – all in the first person plural, even though he is a yachid?

Or should he change the “we” to “I” when he says Kol Nidrei.

Thanks a lot.
