Rav Haim Palagi speaks about the great significance of holding the Sefer Tora during Kol Nidre and if one has the means should certainly attempt to buy this meritorious Mitzvah.
Nevertheless Rav Ben-zion Abba Shaul (Ner Lezion, Yom Kippur) criticizes those who spend excessive amounts on a Ram’s head for the night of Rosh Ashana and the Sefer Tora on Kol Nidrei but do not do the same for their Etrog, which is a Tora obligation. Rav Benzion Mutzafi in Kadosh Lezion adds that one should attemt to kiss each of the Sifrei Torot seven times, as there is a great reason for this according to Kabbalah.
Certain places in Morocco had a custom of reciting Hashkavot (prayers for the departed) for their sages right after Kol Nidre. Interestingly, one can find that this custom was kept in Gibraltar.
Nonetheless, an older Siddur called Beit Hakaporet relates in detail the importance of reciting these Hashkavot on the night of Kippur since even the departed need atonement. Rav Yehuda Ayash comments in his work Zeh Ha'Shulchan; was also the custom in Algeria, Tunisia and Beit El, respectively, we also find that Rav Yitzhak Alfaya in his book that this was also the custom.
Another custom that is followed by the Moroccan community is that “Vehu Rahum” is recited on Yom Kippur at the beginning of Arvit, even if it falls on Shabbat. We find that the Ben Ish Chai (Parashat Vayelech 13) rules that it should not be said when Kippur falls on Shabbat, Rav Yaakov Algazi in his work supports this minhag. Rav Ovadia Yosef supports this in Halichot Olam and Rav Amram Aburbia supports this minhag in Netive Am.
Conclusion: For some their is the minhag to recite Hashkava for Sages of their communities after Veihu Rachum in Arvit of Kippur even if it falls on Shabbat.
Speak with the Rabbi/posek of your community to find out if this customs is one that needs observance.
Have a safe and pleasant Yom Kippur may your name be sealed in the Sefer Chaim!!!
